Production process of Glycolic acid 70%

图片
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 i...
