Ingabe utshwala be-propargyl buyingozi kakhulu?Liyini ithemba lentuthuko yemboni yotshwala be-propargyl?I-Propargyl alcohol, ebizwa ngokuthi i-2-propargyl-1-alcohol, i-3-hydroxymethyl acetylene ne-ethynyl methanol, enefomula ye-molecular C3H4O nesisindo samangqamuzana angu-56.07.Iwuketshezi olungenambala obala olunephunga lamaqabunga anuka kamnandi.Kulula ukuphenduka kubephuzi ngemva kokugcinwa isikhathi eside, ikakhulukazi uma kuvezwe ekukhanyeni.Iwuketshezi oluvuthayo, oluncibilika kalula emanzini, otshwaleni kanye ne-ether.Ingasetshenziswa njenge-rust remover, chemical intermediate, corrosion inhibitor, solvent, stabilizer, njll.
Isimo sokuthuthuka kanye nokuhlaziywa kweProspect of propargyl alcohol industry in China
Utshwala be-Propargyl buyinto ebalulekile yamakhemikhali eluhlaza, esetshenziswa kabanzi emkhakheni wezokwelapha, imboni yamakhemikhali, i-electroplating, izibulala-zinambuzane, ukuxhashazwa kwensimbi namafutha, njll. ngenani eliphakeme elingeziwe, ngokuvamile lilungiswa ngokusabela kwe-formaldehyde ne-acetylene.
E-China, utshwala be-propargyl busetshenziswa kakhulu ekuhlanganiseni izinto zokusetshenziswa kwemithi i-fosfomycin sodium, i-fosfomycin calcium, i-SULFAPYRIDINE kanye nesibulala-zinambuzane i-chlorhexidine, okubalelwa cishe ku-60% wesamba;Cishe u-17% wezinto ezisheshayo zokulinganisa i-nickel nezikhanyisi zisetshenziselwa i-electroplating (i-ejenti yokulinganisa isikhathi eside kanye ne-brightener yi-1,4-butynediol, kodwa ukukhanya kubuthakathaka);Ukuxhashazwa kukawoyela cishe ku-10%;Imboni ye-Metallurgical ibamba cishe u-8%;Ezinye izimboni zenza cishe u-5%.
Ngo-2019, isidingo saseChina sotshwala be-propargyl sasingamathani angama-5088.9, nokunyuka konyaka ngonyaka ngama-7.3%;Ngo-2020, isidingo saseShayina sotshwala be-propargyl sasingamathani angama-5353.5, nokunyuka konyaka ngo-5.2%;Ngo-2021, isidingo sotshwala be-propargyl e-China sasingamathani angama-5717.8, nokunyuka konyaka ngonyaka ngo-6.8%.
I-BASF ingumkhiqizi oyinhloko wotshwala be-propargyl emazweni angaphandle, futhi abakhiqizi abakhulu basekhaya bahlanganisa i-Shandong dong'a fengle chemical, i-Henan Haiyuan amakhemikhali amahle, i-Henan energy kanye neqembu lamakhemikhali i-Hebi Coal Chemical, njll. Njengamanje, i-1,4 enkulu -amabhizinisi okukhiqiza i-butanediol anezinzuzo ezithile zezindleko uma esebenzisa indlela ephansi ye-alkynaldehyde yokubuyisela umkhiqizo ukuze akhiqize utshwala be-propargyl.
