Yini ehlukile i-Butenediol ne-1,4-Butanediol?

I-Butenediol ne-1,4-Butanediolyizinhlanganisela zamakhemikhali ezimbili ezihlukene ezisetshenziswa ezinhlelweni ezahlukene embonini, emikhakheni yezemithi kanye neyokukhiqiza. Naphezu kwamagama afanayo kanye nesakhiwo samangqamuzana, lezi zinhlanganisela ezimbili zinokuhluka okuningana okubenza bahluke komunye nomunye.

Okokuqala,I-Butenediol ne-1,4-Butanediolabe namafomula ahlukene wamangqamuzana. I-Butenediol inefomula, i-C4H6O2, kuyilapho i-1,4-Butanediol inefomula ye-C4H10O2. Lo mehluko ekwakhekeni kwamangqamuzana nefomula uthinta izakhiwo zawo ezingokomzimba namakhemikhali, njengamaphoyinti ancibilikayo nabilayo, ukuncibilika, nokusebenza kabusha.

Okwesibili,I-Butenediol ne-1,4-Butanediolzibe nokusetshenziswa kanye nezicelo ezahlukene. I-Butenediol isetshenziswa ngokuyinhloko ekukhiqizeni i-polyester ne-polyurethane resins, izinto zokunamathisela, ama-plasticizers, nanjenge-solvent yopende nezingubo. Ngokuphambene, i-1,4-Butanediol isetshenziswa njenge-feedstock yokukhiqiza amakhemikhali amaningana, kuhlanganise ne-gamma-butyrolactone (GBL), i-tetrahydrofuran (THF), ne-polyurethanes. Ukwengeza, isetshenziswa ekwenzeni izingxenye zezimoto, i-electronics, imithi, kanye nezimonyo.

Okwesithathu,I-Butenediol ne-1,4-Butanediolbabe nobuthi obuhlukene kanye nezingozi ezihlobene nokusetshenziswa kwabo. I-Butenediol ihlukaniswa njengento ecasula isikhumba namehlo futhi ingabangela ukucasuka kokuphefumula lapho ihogelwa. Ngakolunye uhlangothi, i-1,4-Butanediol ihlukaniswa njenge-carcinogen engaba khona kanye ne-mutagen futhi ibeka ingozi yobuthi obunzima kubantu uma idliwe noma ihoxiswa.

Okokugcina,I-Butenediol ne-1,4-Butanediolbanezinqubo ezahlukene zokukhiqiza. Ukukhiqizwa kwe-Butenediol kuhilela ukusabela kwe-anhydride yesilisa ngotshwala, njenge-ethylene glycol noma i-propylene glycol. Ukukhiqizwa kwe-1,4-Butanediol, ngakolunye uhlangothi, kuhilela i-hydrogenation ye-succinic acid, etholakala ku-anaerobic fermentation yezinsiza ezivuselelekayo, ezifana nesitashi sommbila noma umoba.

Ekuphetheni,I-Butenediol ne-1,4-Butanediolyizinhlanganisela zamakhemikhali ezimbili ezihlukene ezinamafomula amangqamuzana ahlukene, ukusetshenziswa, ubuthi, ubungozi, nezinqubo zokukhiqiza. Nakuba zabelana ngokufana okuthile, njengokusetshenziswa kwazo lapho kukhiqizwa ama-polyurethanes, zinezakhiwo ezihlukile ezizenza zifanelekele ukusetshenziswa okuhlukile. Kubalulekile ukuqonda lo mehluko ukuze kuqinisekiswe ukusetshenziswa kwabo okuphephile nokusebenza kahle ezimbonini nasezinhlelweni ezahlukahlukene.
