Introduction
Ethylene glycol butyl ether is also known as 1,4-butanediol dimethyl ether. The following is an introduction to its nature, use, manufacturing method and safety information:Quality:1. Ethylene glycol butyl ether is a colorless and flammable liquid.2. It has low toxicity and good solubility, and is soluble in water, alcohols and ether solvents.Use:Ethylene glycol butyl ether has strong solubility and good dispersibility, and is widely used in various industries.1. As a dispersant and thinner in paints and paints.2. Solvents used in the manufacture of plastics, rubber, and fibers.3. Used as reaction medium and catalyst carrier.4. Used as a cleaning agent and degreaser in the electronics industry.5. Used in the manufacture of inks, pigments and dyes, etc.Method:Ethylene glycol butyl ether can be prepared by transesterification reaction of 1,4-butanediol with methyl tert-butyl ether. Reaction conditions can be facilitated using acid catalysts (such as sulfuric acid) and high temperatures.Safety Information:1. Ethylene glycol butyl ether has low toxicity, but it is still a flammable liquid, and attention should be paid to fire and explosion protection.2. Avoid direct contact with skin and eyes to prevent inhalation or ingestion.3. When storing and operating, it should be kept away from ignition and oxidants.4. It should be stored in an airtight container and avoid contact with air to prevent volatilization and oxidation.5. Appropriate protective equipment such as chemical gloves, goggles, and protective clothing should be used when operating.
