Yintoni eyahlukileyo iButenediol kunye ne-1,4-Butanediol?

I-Butenediol kunye ne-1,4-Butanediolzikhompawundi ezimbini ezahlukeneyo zeekhemikhali ezisetyenziswa kwizicelo ezahlukeneyo kushishino, amayeza, kunye namacandelo emveliso. Ngaphandle kwamagama afanayo kunye nokwakheka kweemolekyuli, ezi khompawundi zimbini zineyantlukwano ezininzi ezibenza bahluke omnye komnye.

Okokuqala,I-Butenediol kunye ne-1,4-Butanediolzineefomula ezahlukeneyo zemolekyuli. I-Butenediol ine-formula, i-C4H6O2, ngelixa i-1,4-Butanediol ine-formula ye-C4H10O2. Lo mahluko kwisakhiwo seemolekyuli kunye nefomula ichaphazela iimpawu zabo zomzimba kunye neekhemikhali, ezifana nokunyibilika kunye namanqaku abilayo, ukunyibilika, kunye nokusebenza kwakhona.

Okwesibini,I-Butenediol kunye ne-1,4-Butanediolzineendlela ezahlukeneyo zokusebenzisa kunye nokusetyenziswa. I-Butenediol isetyenziswa ikakhulu ekwenzeni i-polyester kunye ne-polyurethane resins, i-adhesives, i-plasticizers, kunye ne-solvent yepeyinti kunye neengubo. Ngokwahlukileyo, i-1,4-Butanediol isetyenziselwa ukuveliswa kweekhemikhali ezininzi, kuquka i-gamma-butyrolactone (GBL), i-tetrahydrofuran (THF), kunye ne-polyurethanes. Ukongeza, isetyenziselwa ukwenza izinto zemoto, i-elektroniki, amayeza, kunye nezinto zokuthambisa.

Okwesithathu,I-Butenediol kunye ne-1,4-Butanediolzineetyhefu ezahlukeneyo kunye nemingcipheko ehambelana nokusetyenziswa kwazo. I-Butenediol ihlelwa njengento ecaphukisa ulusu kunye namehlo kwaye inokubangela ukucaphuka kokuphefumula xa ifakwe. Ngakolunye uhlangothi, i-1,4-Butanediol ihlelwa njenge-carcinogen enokwenzeka kunye ne-mutagen kwaye ibeka umngcipheko we-toxicity eyingozi kubantu xa ifakwe okanye ifakwe.

Okokugqibela,I-Butenediol kunye ne-1,4-Butanediolzineenkqubo ezahlukeneyo zemveliso. Ukuveliswa kweButenediol kubandakanya ukuphendula kwe-anhydride ye-maleic kunye notywala, njenge-ethylene glycol okanye i-propylene glycol. Ukuveliswa kwe-1,4-Butanediol, ngakolunye uhlangothi, kubandakanya i-hydrogenation ye-succinic acid, efunyenwe kwi-anaerobic fermentation yezibonelelo ezihlaziyiweyo, ezifana ne-corn starch okanye i-sugar cane.

Ukuququmbela,I-Butenediol kunye ne-1,4-Butanediolzikhompawundi ezimbini ezahlukeneyo zeekhemikhali ezinefomula ezahlukeneyo zemolekyuli, ukusetyenziswa, ubutyhefu, umngcipheko, kunye neenkqubo zokuvelisa. Ngelixa babelana ngezinto ezifanayo, ezinjengokusetyenziswa kwabo ekwenzeni i-polyurethanes, baneempawu ezizodwa ezibenza bafanelekele izicelo ezahlukeneyo. Kubalulekile ukuqonda lo mahluko ukuqinisekisa ukusetyenziswa kwabo ngokukhuselekileyo nangempumelelo kumashishini ahlukeneyo kunye nokusetyenziswa.
