Glycolic acid is the crystal of a colorless, deliquescence. Soluble in water, soluble in methanol, ethanol, ethyl acetate and other organic solvents, soluble in ethyl ether and not soluble in hydrocarbons. Both alcohol and acid have a duality that is heated to boiling point decomposition. For organic synthesis, etc. It is usually hydrolyzed by chloroacetic acid in alkaline conditions.
Action and purpose editing
1, chemical cleaning: glycolic acid solution is mainly used as detergent, 70% 2% of glycolic acid and 1% formic acid mixed acid is a kind of high efficiency, low cost of cleaning agents, can be used for air conditioning, boilers, power plant pipelines, condensers, heat exchangers and other major cleaning materials.
2, biodegradable materials, widely used in the preparation of the body preparetions slow-release drug system, preparetions repair equipment, biological absorption surgical sutures, materials for artificial bones and organs, etc., has a development prospect very much. Polylactic acid and polyglycolic acid have become the development focus of new materials.
3, fungicides, because of the special structure of glycolic acid containing hydroxyl and carboxyl, can be formed through coordination bond between the metallic cations hydrophilic chelate, therefore on iron oxidizing bacteria growth has obvious inhibitory effect, can be used as a disinfectant, can also be used in a variety of ore flotation inhibitor.
4, daily chemicals: 99% glycolic acid is a better curative effect to remove dead skin and hair potions, can synthesize resist skin aging, whitening cosmetics raw fruit acid, can achieve the effect of moisturizing, nourish skin, promote the skin update. Glycolic acid molecular weight is very small, it can penetrate the skin pores, effectively in a short period of time to solve the skin aging, wrinkles, spots, acne problems, therefore unanimous esteem by medical hairdressing industry.
5, plating surface treatment: glycolic acid can also be used in electroplating industry, glycolic acid sodium salt, potassium can be used as electroplating additives, also can be electroplated grinding, metal pickling, leather dyeing and tanning agents of green chemical raw materials. Glycolic acid is also a compound agent of chemical nickel plating, which has the advantages of corrosion resistance, quick reaction and good finish, which is the best preparation material for improving the quality of nickel plating.
In addition, glycolic acid can be used in the textile industry for the crosslinking agent of the wool fiber and cellulose fabric and the crosslinking agent of the carboxylic fiber fabric. It can also be used as adhesives, oil demulsifiers, welding agents and coatings, and various medicines, pesticides and chemical additives.
