Hexamethylphosphoramide (HMPA) (CAS: 680-31-9) bụ soluble na polar na ndị na-abụghị polar solvents.Ọ na-adabakwa n'ihe ndị a na-ejikarị plasticizers dị ka dioctyl phthalate, dioctyl sebacate, na triphenyl phosphite n'ụzọ ọ bụla.Zere kọntaktị na akpụkpọ ahụ.Ekwesịrị mechie akpa ya nke ọma iji gbochie ntapu na mmịpụta mmiri ka emebi emebi Hexamethylphosphoramide bụ ihe na-eme ka ọkụ na-eme ka PVC dịkwuo mma, na-enye ezigbo ihe mgbochi ịka nká nke ngwaahịa dị n'èzí nwere nguzogide ihu igwe dị mma, yabụ mara ya dị ka onye na-ahụ maka ihu igwe na-arụ ọrụ nke ọma nke PVC. .Mgbakwunye ngwaahịa a na ihe nkiri PVC nwere ike imeziwanye ma ihu igwe na-eguzogide oyi na nguzogide oyi yana ibelata nhazi okpomọkụ site na 10 ℃.1. Enwere ike iji ya dị ka onye na-emepụta ihe na-emepụta ihe na-emepụta ihe na-arụ ọrụ nke ọma nke PVC na ụdị ndị ọzọ nke ngwaahịa resin na mkpuchi chlorine.2. Ngwaahịa ahụ bụ ihe mgbaze ihu igwe nke polyvinyl chloride na ihe mgbaze polar mara mma, na-enwe mmetụta dị ukwuu na nkwụsị okpomọkụ dị ala na iguzogide ịka nká nke ihe nkiri ugbo;ọ bụ ihe mgbaze pola na-esi n'ọtụtụ na-arụ ọrụ nke bụ aprotic.Enwere ike iji ya dị ka ihe mgbaze nke njikọ polymer nwere mmetụta pụrụ iche na njikọ nke polyphenylene sulfide na aromatic polyamide na ndị ọzọ.Ngwaahịa a, dị ka onye na-emekọ ihe nke propylene polymerization catalyst, mgbe a na-enye ya na roba ethylene propylene, nwere ike imeziwanye ngwa agha na mgbochi mmanụ nke nke ikpeazụ.A pụkwara iji Hexamethylphosphoramide mee ihe dị ka gas chromatographic fixative, ultraviolet inhibitor, mmanụ ọkụ roket maka iweda ebe na-ajụ oyi na ọgwụ sterilizers.3. Ọ dị irè na-abụghị proton mgbaze;dị ka fixative nke chromatography gas (okpomọkụ ojiji kachasị elu: 35 ° C na methanol dị ka ihe mgbaze);eji maka nkewa na nyocha nke hydrocarbons;maka nkewa nke alkanes, alkenes na alkynes;osooso nke stereo-kpọmkwem mmeghachi omume;Ultraviolet inhibitor nke PVC.
