Product Description

Introduction of Pharmaceutical Intermediates

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.

production method of Pharmaceutical Intermediates

1. Oxalic acid electrolysis oxalic acid aqueous solution by electrolysis reduction, resulting in dilute glyoxylic acid solution, and then by evaporation, concentration, freezing, filtration gradually concentrated, and finally qualified packaging.
2. Glyoxal oxidation Pharmaceutical Intermediates in the role of the catalyst by air or oxygen oxidation, the formation of glyoxylic acid, and then refined by the finished product. In addition, dichloroacetic acid and sodium methoxide condensation of sodium dimethoxy acetic acid, and hydrochloric acid hydrolysis to generate glyoxylic acid.
3. Dichloroacetic acid method of sodium methoxide and methanol into the reaction tank, heated to 40 ~ 50 ℃, slowly dropping dichloroacetic acid, after the completion of reflux reaction 2h, condensation is completed, and then cooled to room temperature, filtration, methanol washing , Combined to wash the filtrate, that was dimethoxy acetic acid sodium methanol solution. The solution was concentrated under reduced pressure to dryness, and 2.8 parts of hydrochloric acid was added to the water bath and heated to a paste to obtain a hydrolyzate. The temperature was raised to 90 ° C and cooled to about 10 ° C. The mixture was filtered and separated to obtain a product

Usage of Pharmaceutical Intermediates

Glyoxylic acid Pharmaceutical Intermediates used as a cosmetic flavoring agent and fixing agent, also used in pharmaceuticals.
