ʻO DI METHYL ETHANOLAMINE (DMEA)

ʻO DI METHYL ETHANOLAMINE, he hui organik, ke ʻano kemika C5H13NO2, no ka wai ʻaila melemele ʻole a ʻeleʻele paha, hiki ke hui pū ʻia me ka wai, ka waiʻona, a hoʻoheheʻe iki ʻia i loko o ka ether. Hoʻohana nui ʻia ma ke ʻano he emulsifier a me ka mea hoʻomoʻa kinoea waikawa, mea hoʻomalu kumu waikawa, mea hoʻouluulu polyurethane, a hoʻohana pū ʻia hoʻi ma ke ʻano he lāʻau antitumor e like me ka nitrogen mustard hydrochloride intermediate.

Nā Waiwai:He ʻala ammonia kēia huahana, ʻaʻohe kala a wai melemele paha, hiki ke lapalapa. Hiki ke hui pū ʻia me ka wai, ethanol, benzene, ether a me ka acetone. ʻO ka nui pili 0.8879, ka paila ʻana he 134,6℃. Ka hau ʻana he 59. O℃. Ka hoʻā ʻana he 41℃. Ka lapalapa (kīʻaha hāmama) 40℃. Viscosity (20℃) 3.8mPa. s. ʻO ka helu kuhikuhi refractive he 1.4296.

ʻAno hoʻomākaukau:

1. Ke kaʻina hana ʻana o ka ethylene oxide e ka dimethylamine a me ka ethylene oxide ammonia, ma o ka distillation, distillation, dehydration.

2. Loaʻa ke kaʻina hana Chloroethanol ma o ka saponification o chloroethanol a me ka alkali e hana i ka ethylene oxide, a laila synthesized me dimethylamine.

 Nā Hoʻohana o DMEA：

He haʻahaʻa loa ka hana catalytic o N,N-dimethylethanolamine DMEA, a he liʻiliʻi kona hopena i ka piʻi ʻana o ka huʻa a me ka hopena gel, akā he alkalinity ikaika ko ka dimethylethanolamine DMEA, hiki ke hoʻopau pono i ka nui o nā mea i loko o nā ʻāpana hua. ʻO nā waikawa, ʻoi aku hoʻi i nā isocyanates, no laila e mālama i nā amine ʻē aʻe i loko o ka ʻōnaehana. ʻO ka hana haʻahaʻa a me ka hiki ke hoʻopau kiʻekiʻe o ka dimethylethanolamine DMEA e hana ma ke ʻano he buffer a he mea maikaʻi loa ia i ka wā e hoʻohana ʻia ai me ka triethylenediamine, i hiki ai ke hoʻokō ʻia ka wikiwiki o ka hopena i makemake ʻia me nā haʻahaʻa haʻahaʻa o ka triethylenediamine.

He ākea nā hoʻohana o Dimethylethanolamine (DMEA), e like me: hiki ke hoʻohana ʻia ka dimethylethanolamine DMEA e hoʻomākaukau i nā uhi wai-dilutable; ʻO ka dimethylethanolamine DMEA kahi mea maka no ka dimethylaminoethyl methacrylate, i hoʻohana ʻia e hoʻomākaukau i nā mea anti-Static, nā mea hoʻomaʻamaʻa lepo, nā mea conductive, nā mea hoʻohui pepa a me nā flocculants; Hoʻohana ʻia ka dimethylethanolamine DMEA i nā mea mālama wai e pale aku i ka pala o ka paila.

I loko o ka huʻa polyurethane, ʻo dimethylethanolamine DMEA kahi mea hoʻouluulu a me kahi mea hoʻouluulu reactive, a hiki ke hoʻohana ʻia ka dimethylethanolamine DMEA i ka hana ʻana o ka huʻa polyurethane palupalu a me ka huʻa polyurethane paʻa. Aia kahi hui hydroxyl i loko o ka mole o dimethylethanolamine DMEA, hiki ke hana me ka hui isocyanate, no laila hiki ke hui pū ʻia ka dimethylethanolamine DMEA me ka mole polymer, a ʻaʻole ia e like me ka volatile e like me triethylamine.

Ka hoʻopili huahana:Ke hoʻohana nei i ka ʻōpala pahu hao, ʻo ke kaumaha ʻupena he 180kg no kēlā me kēia pahu. E mālama i kahi anuanu a me ka ea. E mālama a lawe e like me nā kemika lapalapa a me nā mea ʻawahia.
