Monoglycerides purification Solution
Phunzirani kuti utomoni wa epoxy uyeretsedwe ku distillation ya mamolekyulu kuti mupeze utomoni wochepa wa chlorine epoxy.
Glycerin monostearate (Glycerin monostearate, yofupikitsidwa monga GMS), kulemera kwa maselo 358, mankhwala ogulitsa mafakitale nthawi zambiri amakhala achikasu ngati sera kapena flakes, kupatulapo omwe ali ndi monostearate Kuwonjezera pa esters, ilinso ndi ma diesters ndi triesters ochepa, omwe alibe kukoma, onunkhira komanso opanda poizoni. Ndiosavuta kuyimitsa ndi madzi ndipo ndi emulsifier yamadzi-mu-mafuta. Koma chifukwa cha mphamvu zake zopangira emulsifying, zitha kugwiritsidwanso ntchito ngati mafuta opaka m'madzi. Itha kugwiritsidwa ntchito ngati pulasitiki, wotulutsa nkhungu, antistatic agent, lubricant, etc.
Ndondomeko yopanga:
glycerin ndi mafuta a hydrogenated amachititsidwa ndi esterification ndikusefedwa kuti achotse zonyansa, ndipo yankho lomwe limapangidwa limasinthidwa ndi sodium hydroxide kuti mupeze chinthu chosapangana. Zopangidwazo zimayikidwa pa membrane ndi magawo awiri a molecular distillation kuti achotse glycerol, mafuta acids aulere, diglycerides ndi triglycerides, motsatana. Glycerides, ndipo pamapeto pake amapeza ma monoglycerides apamwamba kwambiri.
