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

MEA ikhoza kupangidwa pochita ammonia/madzi ndi ethylene oxide pamphamvu ya 50-70 bar kuti ammonia asungidwe mumadzimadzi. Njirayi ndiyowopsa ndipo sifunikira chothandizira chilichonse. Chiŵerengero cha ammonia ndi ethylene oxide chimagwira ntchito yofunika kwambiri posankha zomwe zimapangidwira. Ngati ammonia amachitira ndi mole imodzi ya ethylene okusayidi, monoethanolamine aumbike, ndi mamolekyu awiri ethylene okusayidi, diethanolamine aumbike pamene ndi timadontho-timadontho atatu a ethylene okusayidi triethanolamine anapanga. Pambuyo pazimenezi, distillation ya zotsatira zosakaniza ikuchitika choyamba kuchotsa owonjezera ammonia ndi madzi. Kenako ma amines amasiyanitsidwa pogwiritsa ntchito masitepe atatu a distillation.

Monoethanolamine ntchito reagents mankhwala, mankhwala, mankhwala, zosungunulira, utoto intermediates, accelerators mphira, dzimbiri zoletsa ndi surfactants, etc. Amagwiritsidwanso ntchito ngati asidi mpweya absorbents, emulsifiers, plasticizers, mphira vulcanizing wothandizila, kusindikiza ndi utoto nsalu Whitening agent. anti-moth wothandizira, etc. Angagwiritsidwenso ntchito monga plasticizer, vulcanizing wothandizila, accelerator ndi thovu wothandizila kupanga utomoni ndi mphira, komanso intermediates mankhwala ophera tizilombo, mankhwala ndi utoto. Komanso ndi zopangira zotsukira kupanga, emulsifiers kwa zodzoladzola, etc. Textile makampani monga kusindikiza ndi utoto brightener, antistatic wothandizila, odana ndi njenjete wothandizira, detergent. Itha kugwiritsidwanso ntchito ngati choyezera mpweya wa carbon dioxide, chowonjezera cha inki, ndi chowonjezera cha petroleum.
