methylated methylol urea resin - Introduction
Methyl etherated methylol urea (methyl ether urea) is an organic compound with the chemical formula CH3OC(O)NHC(O)NH2. The following is a description of the properties, uses, preparation and safety information of methyl etherized methylol urea:
Nature:
Methyl etherated methylol urea is a colorless crystalline solid with high solubility and is readily soluble in water and most organic solvents. It has both volatile and non-volatile forms. At room temperature, methyletherized methylol urea is stable, but needs to be protected from light.
Use:
Methyl etherized methylol urea has a variety of uses in the chemical industry. It is often used as an intermediate in organic synthesis for the synthesis of other compounds, such as rubber additives, dyes and pesticides. In addition, methyl-etherized methylol urea can also be used as a crosslinking agent and a surface treatment agent for resins.
Preparation Method:
The preparation of methyl-etherized methylol ureas is generally obtained by methanolysis with the reaction of isocyanates. The specific steps are: firstly reacting isocyanate with methanol to generate methyl ether isocyanate, and then reacting with urea under alkaline conditions to obtain methyl etherized methylol urea.
Safety Information:
Methyl-etherized methylol urea is relatively safe when properly stored and used. However, it can be irritating to the skin and eyes. In contact, care should be taken to avoid direct contact with the skin and eyes, and maintain good ventilation conditions. If you feel unwell or accidentally inhale, you should seek medical attention immediately.
