Monoethanolamine (MEA) CAS No. 141-43-5

Hiki ke hana ʻia ka MEA ma o ka hana ʻana i ka ammonia/wai me ka ethylene oxide ma ke kaomi ʻana o 50-70 bar e mālama i ka amonia i loko o ka pae wai. He exothermic ke kaʻina hana a ʻaʻole koi i kekahi catalyst. ʻO ka lakio o ka ammonia a me ka ethylene oxide ka mea nui i ka hoʻoholo ʻana i ke ʻano o ka hui ʻana. Inā hana ka ammonia me hoʻokahi mole o ka ethylene oxide, ua hoʻokumu ʻia ka monoethanolamine, me ʻelua mau mole o ka ethylene oxide, ua hoʻokumu ʻia ka diethanolamine a me nā mole ʻekolu o ka ethylene oxide triethanolamine. Ma hope o ka hopena, lawe mua ʻia ka distillation o ka hui ʻana e hoʻoneʻe i ka amonia a me ka wai. A laila hoʻokaʻawale ʻia nā amine me ka hoʻohana ʻana i kahi hoʻonohonoho distillation ʻekolu.

Hoʻohana ʻia ka Monoethanolamine e like me nā reagents kemika, nā pesticides, nā lāʻau lapaʻau, nā mea hoʻoheheʻe, nā mea hoʻoheheʻe wai, nā accelerators, corrosion inhibitors a me surfactants, etc. anti-moth agent, etc. Hiki ke hoʻohana ʻia e like me ka plasticizer, vulcanizing agent, accelerator a me ka huʻihuʻi no nā resins synthetic a me ka rubber, a me nā intermediates no nā pesticides, nā lāʻau lapaʻau a me nā kala. He mea maka no ka synthetic detergents, emulsifiers no cosmetics, etc. Textile oihana e like me ka pa'i a me ka dyeing brightener, antistatic agent, anti-moth agent, detergent. Hiki ke hoʻohana ʻia ma ke ʻano he carbon dioxide absorber, ink additive, a me ka petroleum additive.
