Txais tos muas Hexamethylphosphoramide CAS 680-31-9 los ntawm peb.Hexamethylphosphoric triamide, tseem hu ua hexaphosphoramide thiab hexamethylphosphoramide, yog npaj los ntawm cov tshuaj tiv thaiv ntawm dimethylamine thiab phosphorus oxychloride. Molecular hnyav 179.2. Nws yog xim tsis muaj xim lossis lub teeb daj pob tshab kua. Me ntsis fishy thiab astringent. Soluble nyob rau hauv polar thiab non-polar solvents. Nws yog miscible nrog cov plasticizers xws li dioctyl phthalate, dioctyl sebacate, thiab triphenyl phosphite nyob rau hauv ib qho kev faib ua feem. Toxicity zoo ib yam li cov phosphate esters. Tsis txhob kov cov tawv nqaij. Lub thawv yuav tsum tau kaw kom nruj kom tsis txhob muaj dej ntws tawm thiab kev puas tsuaj vim kev nqus dej.

Siv los ua tus neeg ua haujlwm zoo los tiv thaiv corrosion rau polyvinyl chloride thiab lwm yam khoom siv tshuaj chlorine thiab txheej txheej.
Cov kuab tshuaj aprotic zoo; theem chromatographic nyob ruaj ruaj tov (qhov siab tshaj plaws kev khiav hauj lwm kub yog 35 ° C, hnyav yog methanol), sib cais thiab tsom xam ntawm hydrocarbon tebchaw, sib cais ntawm alkanes, alkenes thiab alkynes; accelerator rau stereospecific tshuaj tiv thaiv; UV inhibition ntawm polyvinyl chloride tus neeg sawv cev.
Feem ntau siv cov kuab tshuaj aprotic. UV inhibitor ntawm polyvinyl chloride, huab cua-resistant hnyav thiab zoo heev polar hnyav, tshuaj sterilant, thiab lwm yam.
