Physicochemical Property of DL-Methionine powder
DL-Methionine Raw Materials White flaky crystals or crystalline powder from alcohol, slightly sweet, with special smell. No optical rotation. Soluble in water, dilute acid and dilute alkali, slightly soluble in 95% alcohol, insoluble in ether.
Production methodprocess of DL-Methionine powder
In the presence of formic acid and copper acetate, propionaldehyde and methyl mercaptan condense to form 3-methylthiopropionaldehyde. Then mixed with sodium cyanide and ammonium bicarbonate solution.
Reacted at 90℃ to obtain methylthioethylglycolide. Without separation and purification, it can be heated to 180°C together with 28% sodium hydroxide solution and hydrolysed to produce sodium methionine. Neutralisation with hydrochloric acid gives DL-Methionine powder .
