Iimveliso
Ubungcali kwimveliso yotywala bepropargyl, 1,4 butynediol kunye ne-3-chloropropyne
Inkqubo yokuveliswa kotywala bePropargyl kunye nohlalutyo lwemarike
Iipropati kunye nokusetyenziswa kwe-2 ye-propargyl alcohol
2.1 Umsebenzi ogqwesileyo womphezulu kunye nokusasazwa
Utywala bepropargyl bune-polarity eqinile kunye ne-hydrophilicity, kuba iqulethe -OH, kunye ne-hydrophobicity kukuba iqulethe iqela le-hydrocarbon, kuba ezi zakhiwo zenza i-propargyl alcohol njenge-surfactant ye-non-ionic, ebonisa ukusebenza okugqwesileyo, kunye ne-foaming ephantsi, i-defoaming kunye nokumanzi.Uninzi lwee-agent zokumanzisa zibhuqa ngokulula, ngelixa uninzi lwee-agent ezikhupha amagwebu zinobumanzi obumdaka.Xa kuthelekiswa nezinye ii-surfactants, ialkyl alcohols inobunzima obuncinci bemolekyuli, ukusasazwa ngokulula, ukusasazwa kakuhle, ukumanzisa kakuhle kunye negwebu eliphantsi.Ngakolunye uhlangothi, i-alkyl alcohols iqulethe i-hydrocarbon base branched chain groups, uninzi lwamaqela amancinci (ngokubanzi i-methyl), kukho amaqela amabini e-polar kwisakhiwo.Ngenxa yolu lwakhiwo lweekhemikhali, ialkyl alcohols inokumanzisa okuhle.Ngakolunye uhlangothi, amatyathanga e-alkyl-branched alkyl-branched alcohol in propargyl alcohol anokunciphisa umtsalane phakathi kweeamolekyu ezingabamelwane kwaye zenze ifilimu yokwandisa kunye nokuphefumla kumda wolwelo lwegesi.Ngoko ke, ayenzi nje kuphela i-foam ngokwayo, kodwa inamandla athile okuhlamba ugwebu, kwaye inokuxutywa kunye nezinye ii-agent ezikhuphayo ukuze zidlale indima enkulu.
2.2 I-metal corrosion inhibition egqwesileyo
Okwangoku, i-metal corrosion inhibitors esetyenziswa kwimidiya ye-acidic ininzi i-organic compounds, enomthamo oqinileyo we-adsorption kwiindawo zetsimbi.Isakhiwo se-molecular ye-propargyl alcohol ibandakanya amaqela e-polar kunye namaqela angenayo i-polar.Yi-adsorbent ye-organic corrosion inhibitors.Kwelinye icala, amaqhina olungelelaniso abunjwe phakathi kotywala obunxilisayo kunye neeathom zentsimbi zikhuthaza ukufakwa kotywala kumkhamo othile.Ngelo xesha, i-PI bond kwi-propargyl alcohol molecule iyancipha, i-triple bond iyasebenza, kwaye iqela le-polar hydroxyl lisondele kwibhondi ye-acetylene, eyandisa i-adsorption.Kwi-alkaline medium, iproparynyl alcohol inokubhengeza iLangmuir kwi-aluminiyam esulungekileyo, enesiphumo esihle sokuthintela ukubola.Utywala bepropargyl kungenxa yokusebenza kwayo okugqwesileyo, inoluhlu olubanzi kakhulu lokusetyenziswa, ikakhulu olusetyenziswa kwimidibaniso yamayeza, i-copper okanye i-nickel plating polish, i-pesticide ephakathi.Ukongeza, i-propargyl alcohol nayo ingasetyenziswa njenge-corrosion inhibitor yobushushu obuphezulu, uxinzelelo oluphezulu kunye noxinzelelo oluphezulu lwe-hydrochloric acid kwi-oyile kunye negesi yendalo.
2.3 Ukusetyenziswa kotywala bepropargyl
① Iziphakathi ezibalulekileyo kwi-organic synthesis: kwishishini lamachiza, iproparynol yinto ebalulekileyo ephakathi ye-sodium fosfomycin, i-calcium fosfomycin, i-sulfadiazine, kwaye isetyenziselwa ukuveliswa kwe-alylal alcohol, i-acrylic, i-vitamin A kunye nezinye iimveliso zamachiza;② Umshicileli we-Electroplating okhanyayo: iikhompawundi zotywala zepropargyl zinokufana okuhle kunye nokukhazimla, kunye nokumelana nokukhanya okulungileyo kwi-nickel plating.Ngaba isizukulwana sesine se-nickel plating brightener, esisetyenziswa ngokubanzi kushishino lwe-electroplating;③ Ukususwa komhlwa okubalulekileyo: utywala beproparynyl kunye neekhompawundi zayo ezisezantsi zinokuthintela ukubola kwentsimbi, ubhedu, i-nickel kunye nezinye izinyithi ngezinto ze-asidi ezifana ne-acetic acid, i-phosphoric acid, i-sulfuric acid, i-hydrochloric acid;(4) Uphuhliso lwe-petroleum: ubushushu obuphezulu, uxinzelelo oluphezulu kunye noxinzelelo oluphezulu lwe-hydrochloric acid corrosion inhibitors zizinto eziphambili ezisebenzayo ze-acid corrosion inhibitors kwi-oyile kunye ne-gas Wells;⑤ ingasetyenziswa njenge-solvent, i-chlorinated hydrocarbon stabilizer, i-fungicide kunye nezinye izinto eziluhlaza.
Inkqubo yokuvelisa
Okwangoku, eyona ndlela isetyenziswa kakhulu yokulungiselela utywala bepropargyl ekhaya nakwamanye amazwe kukusabela kwe-formaldehyde kunye ne-acetylene ukuvelisa i-propargyl alcohol kunye ne-butynediol, ipropargyl alcohol iyimveliso ye-butynediol.Ngokulungelelanisa umthamo ofanelekileyo wokuthatha igesi ye-acetylene, ukuphucula uxinzelelo lokuphendula, ukumisela ixabiso le-pH elingcono, umlinganiselo we-propargyl alcohol kunye ne-butynediol unokufikelela kwi-1: 1.6, ukwenzela ukuba kuphuculwe ukukhethwa kotywala bepropargyl.Inkqubo: Yongeza i-copper oxygenated catalyst kwi-tank activation, yongeza amanzi okuthambisa, ugxobhoze malunga ne-20min, kwaye uthele umxube we-catalyst kunye namanzi kwi-tank evuselelayo ngepompo.Amanzi athambileyo kunye ne-formaldehyde yongezwa kwi-tank edibeneyo ukuze kulungiswe isisombululo esine-6% ~ 10% ye-formaldehyde.Ulwelo olushukumisayo lwaphonswa kwi-reactor kunye nepompo yokutya ye-plunger ngokwezinga lokuhamba elilinganisiweyo, kwaye i-acetylene compressor yaqalwa ukulungelelanisa izinga lokuhamba kwe-acetylene kunye nokulawula isantya sokuphendula.Ubushushu obuzenzekelayo kunye nenkqubo yokulawula uxinzelelo lwe-reactor yaqalwa ukulawula ubushushu be-reactor kwi-90 ~ 130 ℃ kunye noxinzelelo kwi (2.0±0.1) MPa.Inkqubo yokusabela ijikeleza emva kokukhutshwa, kwaye ukukhutshwa kubuyela kwitanki edibeneyo.Umxholo we-formaldehyde kwizinto eziphathekayo ufunyenwe emva kwe-0.5h.Xa i-formaldehyde eseleyo yayingaphantsi kwe-0.3%, umjikelezo wamiswa kwaye isisombululo sokuphendula sagxothwa kwitanki ephakathi kunye ne-propargyl kunye ne-butanediol contents malunga ne-4% kunye ne-6%, ngokulandelanayo.I-catalyst kwinkqubo yokuvelisa idinga ukutshintshwa rhoqo, kwaye ixesha lokutshintshwa liyi-30 ukuya kwiintsuku ze-40.I-nitrojeni isetyenziswe ngokubambisana ne-catalyst yokususa izinto ezivela kwinkqubo ngexesha lokutshintshwa.Emva kokuhlukana ngoxinzelelo lwe-filtration, i-catalyst eseleyo ifakwe kwi-tank yokugcina i-catalyst echithwe kwaye ivalwe ngamanzi.I-catalyst entsha ibhalwa kwakhona kumjikelo olandelayo we-batching system.
Uhlalutyo lwemarike yotywala ye-Propargyl
I-Dezhou Tianyu Chemical Co., Ltd. yenye yemveliso embalwa yasekhaya ye-propargyl alcohol kunye ne-butanediol amashishini amakhulu, imveliso yonyaka ye-propargyl alcohol 1200T, i-butanediol 2400T, kunye nomgangatho we-BASF waseJamani olinganayo.I-Henan Haiyuan Fine Chemical Co., Ltd. yaphucula kwaye yaphucula iprojekthi ngesiseko senkqubo yokuvelisa i-Shandong Dongfang Le, kunye nemveliso yonyaka ye-1200T propionyl alcohol kunye ne-2400T butanediol.E-China, i-proparynyl alcohol isetyenziswa ikakhulu kwi-synthesis yeziyobisi, i-sodium phosphate, i-calcium phosphate, i-sulfonamide kunye ne-pesticides, i-accounting malunga ne-60% yetotali.I-Nickel plating ekhawulezayo kunye ne-flash plating ibalelwa kwi-17%.Imveliso yeoli imalunga ne-10%;Isabelo sentsimbi simalunga neepesenti ezisi-8;Amanye amashishini athatha malunga ne-5%.Utywala bepropargyl yikhemikhali eyityhefu kakhulu ebuthathaka kwimveliso, ukuthengisa kunye nokusetyenziswa.Liyeza elisezantsi, i-pesticide, imidiya ye-metallurgical kunye nezinye iindawo ezincedisayo okanye enye yamacandelo.Ekupheleni kwe-2017, umthamo osebenzayo wemveliso yasekhaya wawuyi-4,770T / a, kwaye imfuno yayimalunga ne-4,948T / a.Ubonelelo kunye nemfuno ngokusisiseko zilungelelene, kunye nokunqongophala kwamaxesha athile.
Ukuqukumbela
Okwangoku, ukhuphiswano lwemarike yasekhaya yepropanol luyingozi, intsimi yalo enkulu yesicelo yimveliso ye-fosfomycin yemveliso yamachiza, ngolawulo lokusetyenziswa kakubi kwe-antibiotic yesizwe kunye ne-electroplating industry yokukhusela indalo, abasebenzisi bepropanol ezantsi kwixesha elifutshane abazange banyuke.Okwangoku, sizama ukuqhubela phambili inkqubo entsha yokusabela, siphucula rhoqo isivuno sotywala bepropargyl, kwaye sizame ukunciphisa ukusetyenziswa kwamandla kweemveliso zotywala zepropargyl.Ukuphunyezwa kwale misebenzi kuya kunciphisa ngakumbi iindleko zeemveliso zotywala, ukuphucula ukukhuphisana kweemveliso, kunye nokuzama ukuhlangabezana nemfuno yemarike yasekhaya nengaphandle yotywala kunye nochungechunge lweemveliso, ukudala inzuzo yezoqoqosho nentlalontle.
