Abstract
"PREPARAçãO DE AMIDAS DE áCIDO <244>-AMINO CARBOXìLICO". Método de preparação de amidas de ácido <244>-amino carboxílico diretamente a partir de aminonitrilas com altos rendimentos e pureza por hidrólise ácida. O método envolve a preparação do sal da amida tal como amida hidrocloreto diretamente a partir da aminonitrila correspondente na presença de água, um ácido mineral forte tal como HC1 anidro, e um solvente orgânico em que o sal de amida resultante é insolúvel ou substancialmente insolúvel. Solventes orgânicos adequados incluem éteres dialquil, éteres etileno glicol diaquil e álcoois secundários.
