Production process of Glycolic acid 70% Description Glycolic acid  project adopts the production process of cyanide hydrolysis. Glycolonitrile is intermediate product of cyanide hydrolysis method. It is directly sourced from the Glycolonitrile production unit in the original plant area. Directly using Glycolonitrile as a production raw material, it is low investment in production equipment, source of raw materials convenient and stable. It greatly reducing production costs, environmental risks and environmental impact. Process The raw materials stored in various storage tanks in the workshop by pipelines or tank. It is pumped into the reaction kettle of each section by gravity flow or pump metering. Production materials 1. Glycolonitrile 2. Methanol 3. Sulfuric acid 4. Primary water 5. Ammonium hydroxide 1.Glycolonitrile Acid hydrolysis Pour a certain amount of soft water into the hydrolysis kettle, while starting the stirring, slowly add concentrated sulfuric acid into the hydrolysis

Glyoxylic acid 50% for semi-permanent method for straightening curly, frizzy or wavy hair Currently, there are three methods used for straightening curly, frizzy or wavy hair. a. Using a simple treatment with electric plates consisting of two hot plates (at a temperature higher than 100°C). The hair is placed between the two plates and compressed to achieve the desired style. b. Chemical treatment combined with low-temperature mechanical processing: A chemical substance is applied to the hair, which causes a change in the hair when treated at a temperature below 100°C. c. Chemical treatment combined with high-temperature mechanical processing: A chemical substance is applied to the hair and treated at a temperature higher than 100°C. Due to the combination of heat and the chemical substance applied to the hair, this technique can cause more significant changes in the hair than those achieved by other techniques. A semi-permanent method for straightening human hair, comprising the follo

  Production method of Glycolic acid 99% Glycolic acid  is an important organic synthesis intermediate and chemical product. As a new type of fine chemical intermediate, it has many uses, as follows: It can be used as a tanning assistant, water disinfectant, milk shed disinfectant, boiler scale remover. Glycolic acid  can be used as a cleaning agent. A mixed acid composed of 2%  glycolic acid  and 1% formic acid is an efficient and low-cost detergent suitable for cleaning air conditioners. It can produce fiber dyeing agents, detergents, welding agent ingredients, varnish ingredients, copper etchants, adhesives, petroleum demulsifiers, metal integrators. Sodium and potassium salts of  glycolic acid  are used as additives in electroplating solutions. Other uses include electrolytic grinding, metal pickling and leather dyeing. It can also be used as a chemical analysis reagent for organic synthesis and as a daily chemical additive instead of fruit acid. 1.  Glycolic acid solution HOCH2CN+
