1. Glyoxylic acid Pharmaceutical Intermediates consists of an aldehyde group (-cho) and a carboxyl group (-cooh), whose structure is HOCCOOH, molecular C2H2O3. Production methods:1. The solution of oxalic acid electrolytic acid solution has been reduced by electrolysis, producing acetaldehyde dilute solution, and then by evaporation, concentration, freezing and filtration gradually enriched, finally the packaging of the quality products.
2. Glyoxal oxidation Pharmaceutical Intermediates of acetaldehyde is oxidized by air or oxygen under the action of the catalyst, resulting in glyoxalic acid, which is then refined and purified. In addition, dichloroacetic acid is condensed with methanol sodium and sodium dimethoxyacetic acid is obtained.
3. The method of dichloroacetic acid sodium methanol and methanol in reaction tank and heated to 40 ~ 50 ℃, slowly add dichloroacetic acid, reflux reaction 2 h after complete, condensation, then cool to room temperature, filtering, methanol washing, wash filtrate the merger, a quick dimethoxy sodium acetate methanol solution. Solutions of the reduced pressure concentration to dry, add 2.8 servings of hydrochloric acid on the water bath heating, and stir into a paste and hydrolysate, up to 90 ℃, cold from around 10 ℃, filtration, separation, a quick finished product...
Pharmaceutical Intermediates is used as a perfumer and flavouring agent for cosmetics and also for pharmaceutical products.
