Pesticide Intermediates 99% Methyl Tetrahydrophthalic Anhydride Liquid

Methyl tetrahydrophthalic anhydride, also known as methyl tetrahydrophthalic anhydride, which is a light yellow transparent oily liquid, is an important intermediate in electronic information materials, pharmaceuticals, pesticides, resins, and the defense industry, and can also be used in coatings, plasticizers, pesticides and other industries.
The main uses of methyl tetrahydrophthalic anhydride include:
1. Fiber reinforced plastics: used as epoxy resin hardener, can prepare high strength, high toughness fiber reinforced plastics.
2. Coatings and adhesives: as a modifier added to coatings and adhesives to improve their weather resistance and chemical properties.
3. Electronic materials: used as electronic encapsulation materials and electronic adhesives to improve the reliability and heat resistance of electronic components.
4. Compression gaskets, sealing materials and adhesives: used in the manufacture of seals, adhesives and gaskets resistant to chemical solvents.
Preparation of methyl tetrahydrophthalic anhydride
One method of preparing methyl tetrahydrophthalic anhydride is obtained by esterifying cis-hexene dianhydride with methanol in the presence of an acid catalyst.
For safety information, the following precautions should be taken with respect to exposure to 4-methyltetrahydrophthalic anhydride:
1. Skin contact: may cause irritation or allergic reaction, avoid prolonged contact and the possibility of skin sensitization
2. Eye contact: may cause eye irritation, in case of eye contact, immediately flush with plenty of water and seek medical help.
3. Inhalation: Avoid inhalation of dust or gas. If inhaled, remove victim to fresh air and seek immediate medical attention.
4. Ingestion: In case of accidental ingestion, seek medical help immediately.
When using 4-methyltetrahydrophthalic anhydride, follow the guidelines for safe handling and storage and avoid contact with eyes, skin and ingestion. In case of discomfort or inadvertent exposure, seek medical help immediately.

Company information

The company's main import and export products include
（1）Rubber Products are made of rubber raw materials for the rubber mixing machine after refining as raw materials, in the refining of rubber according to the characteristics of the required rubber products and design formulas, and set the required hardness of the product. The products are molded by rubber plate vulcanizing machine. After molding, the products are finally processed with flying edge to make the product surface smooth and burr-free.

（2）Catalysts And Auxiliaries：Generally speaking, a catalyst is a substance that participates in the intermediate course of a chemical reaction and can selectively change the rate of the chemical reaction, while its own quantity and chemical properties remain basically unchanged before and after the reaction. Usually, the catalyst accelerates the chemical reaction, so that the reaction reaches the chemical equilibrium as soon as possible is called catalytic effect, but does not change the equilibrium of the reaction.

Additives are a variety of auxiliary chemicals that need to be added during the production or processing of certain materials and products in order to improve the production process and enhance the performance of the product required for a variety of auxiliary chemicals.
