L-Alanine CAS NO 56-41-7 for Pharma Grade(USP/EP)
Product Name：L-Alanine (Ala)
CAS NO.: 56-41-7
Appearance：white crystalline powder
Product Properties: By propionic acid ammoniation method (1) propionic acid chloride as raw materials, the temperature of 105 ℃ and 3% red phosphorus, in the presence of catalyst into the liquid chlorine to chloride, generate 2 – chlorinated propionic acid, and then into the ammonia solution, with methenamine as catalyst, ammoniation, under the temperature of 60 ℃ is generate 2 – amino propionic acid. Finally the reactant into methanol solution for crystallization, the centrifugal; Dry alpha alanine was finished. 2. The alpha bromine propionic acid chlorination process will alpha bromine propionic acid; Ammonia; Ammonium bicarbonate mixed reflux 7 h, then evaporation to dry, reoccupy ethanol soak wash ammonium bromide, filter out crystallization, again through filtering, adding ethanol crystallization, filtration drying product. 3. Cyanohydrin method of acetaldehyde and hydrocyanic acid reaction generated cyanohydrin, reacts with ammonia amino acrylic get; Then under the condition of alkaline hydrolysis to generate amino propionic acid sodium, L – alanine by ion exchange.
Packing：25kg/drum
