Habka wax soo saarka ee 1,4-butynediol:
Habka isku dhafka acetylene formaldehyde ayaa la qaatay.Acetylene oo ka kooban 80%-90% ayaa lagu cadaadiyaa cadaadiska 0.4-0.5mpa, preheated ilaa 70-80 ℃ waxaana loo diray reactor.Badeecada ceeriin waxaa lagu helaa iyadoo lagu falcelinayo formaldehyde 110-112 ℃ oo leh butyne sida kicinta.Alaabada falcelinta waa la ururiyey oo la safeeyey si loo helo badeecada dhammaatay, iyo wax soo saarku waa khamriga propargyl.
paraformaldehyde waxaa loo isticmaalaa sida walxo ceeriin ah, cyclohexanone waxaa loo isticmaalaa sida dareere ah, acetylene waxaa la geliyaa reactor iyadoo joogitaanka acetylene naxaas ah, heerkulka waxaa lagu hayaa 115-120 ℃.Ka dib marka formaldehyde si buuxda loo beddelo, acetylene waa la joojiyaa, kicinta ayaa la sifeeyaa, iyo xalalka falcelinta ayaa la ururiyey oo dib loo celiyay si loo helo crystalline 1,4-butynediol.
Muuqashada 1,4-butynediol: caddaan ama iftiin jaale ah crystal crystal cad rhombic crystal ( huruud khafiif ah ka dib nuugista qoyaanka)
Magaca Shiinaha: 1,4-butynediol;BOZ;2-butyne-1,4-diol wakiilka iftiinka iftiinka;1,4-butynediol;1,4-dihydroxy-2-butyne;Dihydroxy dimethyl acetylene;Dihydroxymethyl acetylene;2-butyne-1,4-diol.
1,4-butynediol ujeedada ficil:
1,4-butynediol waxaa loo isticmaali karaa in lagu soo saaro butene glycol, butanediol γ- Alaabooyin kiimiko ah oo taxane ah sida butyrolactone ayaa sidoo kale loo isticmaali karaa in lagu soo saaro taxane ah badeecooyin dabiici ah oo muhiim ah sida butene glycol, butylene glycol iyo n-butanol, iyo dheeraad in la sameeyo caagadaha synthetic iyo fiilooyinka synthetic;
1,4-butynediol lafteedu waa dareere wanaagsan.Waxa loo istcimaalaa dhalaalaysa warshadaha elektiroonigga ah iyo sida dhexdhexaadka ah ee isku dhafka dabiiciga ah iyo walxaha qalabka korantada.
