Ngaba utywala obunxilisayo buyingozi kakhulu?Lithini ithemba lophuhliso lweshishini lotywala le-propargyl?I-propargyl alcohol, ebizwa ngokuba yi-2-propargyl-1-alcohol, i-3-hydroxymethyl acetylene kunye ne-ethynyl methanol, kunye ne-molecular formula C3H4O kunye nobunzima be-molecular 56.07.Lulwelo olungenambala olucacileyo olunevumba lamagqabi anuka kamnandi.Kulula ukujika tyheli emva kokugcinwa kwexesha elide, ngakumbi xa kuvezwe ekukhanyeni.Lulwelo olunokutsha, lunyibilika lula emanzini, etywaleni nakwi-ether.Ingasetyenziswa njenge-rust remover, i-chemical intermediate, i-corrosion inhibitor, i-solvent, i-stabilizer, njl.
Ubume boPhuhliso kunye neProspect Analysis yoshishino lotywala lwe-propargyl e-China
Utywala bepropargyl yimveliso ebalulekileyo yeekhemikhali, esetyenziswa ngokubanzi kwiinkalo zeyeza, imboni yeekhemikhali, i-electroplating, i-pesticides, i-steel kunye ne-oil exploition, njl. kunye nexabiso eliphezulu elongezelelweyo, ngokuqhelekileyo lilungiswa ngokusabela kwe-formaldehyde kunye ne-acetylene.
E-China, i-propargyl alcohol isetyenziselwa ukudibanisa izinto eziluhlaza zonyango i-fosfomycin sodium, i-fosfomycin calcium, i-SULFAPYRIDINE kunye ne-pesticide chlorhexidine, ebalwa malunga ne-60% yetotali;Ngokumalunga ne-17% yee-agent ezikhawulezayo zokulinganisa i-nickel kunye nezikhanyisi zisetyenziselwa i-electroplating (i-agent esebenza ixesha elide kunye ne-brightener yi-1,4-butynediol, kodwa ukukhanya kubuthathaka);Ukusetyenziswa kwe-oyile kubalelwa malunga ne-10%;Ishishini leMetallurgical libalelwa kwi-8%;Amanye amashishini athatha malunga ne-5%.
Ngo-2019, imfuno yaseTshayina yotywala be-propargyl yayiziitoni ezingama-5088.9, ngokunyuka konyaka-ngonyaka nge-7.3%;Ngo-2020, imfuno yaseTshayina yotywala bepropargyl yayiziitoni ezingama-5353.5, ngokunyuka konyaka-ngonyaka nge-5.2%;Ngo-2021, imfuno yotywala be-propargyl e-China yayiziitoni ezingama-5717.8, kunye nokunyuka konyaka-ngonyaka nge-6.8%.
I-BASF ngumvelisi oyintloko we-propargyl alcohol kumazwe angaphandle, kunye nabavelisi abakhulu basekhaya babandakanya i-Shandong dong'a fengle chemicals, i-Henan Haiyuan ikhemikhali efanelekileyo, i-Henan amandla kunye neqela lemichiza ye-Hebi Coal Chemical, njl. Okwangoku, i-1,4 enkulu ye-1,4 -amashishini okuvelisa i-butanediol aneenzuzo ezithile zeendleko ukuba asebenzisa i-alkynaldehyde yoxinzelelo oluphantsi lwemveliso yokubuyisela indlela yokuvelisa i-propargyl alcohol.
