Introduction
methyl hydrogen azelate, also known as polycarboxylate, is an important high molecular polymer. It has the following properties:
1. Physical properties: methyl hydrogen azelate is colorless or light yellow liquid, with good solubility, soluble in water, alcohol and organic solvents.
2. Chemical properties: methyl hydrogen azelate is an ester compound with high stability and chemical resistance. It can be hydrolyzed to azelaic acid and methanol.
The main uses of methyl hydrogen azelate include:
1. Polymer preparation: methyl hydrogen azelate can be polymerized with other monomers to prepare high molecular polymers. These polymers have excellent properties and can be used in various industries such as coatings, glues, plastics, fibers, etc.
2. Surfactant: methyl hydrogen azelate can be used as emulsifier, dispersant and wetting agent, widely used in cosmetics, detergents and personal care products and other fields.
The methods for preparing methyl hydrogen azelate are mainly as follows:
1. Transesterification reaction: transesterification reaction is carried out with nonyl alcohol and methyl formate in the presence of acid catalyst to obtain methyl hydrogen azelate.
2. Direct esterification reaction: esterification of nonanol and formate under the action of acid catalyst to generate methyl hydrogen azelate.
Note the following safety information when using and handling methyl hydrogen azelate:
1. methyl hydrogen azelate is irritating and should be rinsed immediately when in contact with skin and eyes.
2. Avoid inhaling the vapor of methyl hydrogen azelate and use it in a well-ventilated place.
3. methyl hydrogen azelate has low toxicity, but long-term and large-scale exposure may have an impact on health, and excessive exposure should be avoided.
4. When storing and transporting methyl hydrogen azelate, keep it away from fire and high temperature to prevent the danger of combustion and explosion.
Please note that before using methyl hydrogen azelate or any chemical, you should carefully read and follow the relevant safety procedures.
