Isbeddellada Horumarinta Maleic Anhydride

IV. Maleic Anhydride Isbeddellada Horumarinta
Shiinaha, kaydka benzene-ka ayaa ku badan oo leh nidaaminta saadka dabacsan, tignoolajiyada gudaha ee wax soo saarka maleic anhydride ee ku salaysan oksaydhka benzene ee 10,000-tan ah waa mid qaangaar ah. Sidaa darteed, tilmaamaha horumarinta ee dhowaan waa sida soo socota:
Dhinac, diiradda saar hagaajinta iyo casriyeynta habka oksaydhka benzene si loo yareeyo isticmaalka iyo wasakhowga, taasoo kor u qaadaysa tartanka.
Dhanka kale, kordhi dadaallada cilmi-baarista iyo horumarinta ee alaabada hoos yimaada ee maleic anhydride. Tusaale ahaan, baahida loo qabo alaabada sida polybutylene terephthalate (PBT) (oo ah wax soo saar hoos yimaada oo ah 1,4-butanediol, BDO) iyo polytetramethylene ether glycol (PTMEG) (oo ah wax soo saar hoos yimaada oo tetrahydrofuran, THF) ayaa si xawli ah u koraya. Suuqa gudaha wuxuu leeyahay farqi weyn oo sahay ah, badeecadahanina waxay inta badan ku tiirsan yihiin soo dejinta.

Maxaad u dooranaysaa Maleic Anhydride? Waa laf-dhabarta resins-ka polyester-ka ee heerka sare ah ee aan buuxin, iyo sidoo kale waxay furaysaa kiimikooyin kala duwan oo hoos yimaada (BDO, THF, iwm.). Noo soo dir fariin hadda si aad u sahamiso xalal MA ah oo loogu talagalay ganacsigaaga!
