The difference between methoxyisopropyl alcohol and isopropyl alcohol_Industrial additives

Isopropyl alcohol

An organic compound, an isomer of n-propanol, also known as dimethylmethanol and 2-propanol. It is also called IPA in the industry. it is. Colorless transparent liquid with an odor similar to a mixture of ethanol and acetone. Soluble in water and most organic solvents such as alcohol, ether, benzene, and chloroform. Isopropyl alcohol is an important chemical product and raw material. Mainly used in pharmaceuticals, cosmetics, plastics, spices, coatings, etc. On October 27, 2017, the World Health Organization’s International Agency for Research on Cancer released a preliminary reference for the list of carcinogens. The use of strong acids to produce isopropyl alcohol is in the list of Class 1 carcinogens, and isopropyl alcohol is in the list of Class 3 carcinogens.

Applications of isopropyl alcohol

It has a wide range of uses as organic raw materials and solvents. As chemical raw materials, it can produce acetone, hydrogen peroxide, methyl isobutyl ketone, diisobutyl ketone, isopropylamine, isopropyl ether, isopropyl chloride, as well as fatty acid isopropyl ester and chlorinated fatty acid isopropyl ester. wait. In fine chemicals, it can be used to produce isopropyl nitrate, isopropyl xanthate, triisopropyl phosphite, aluminum isopropoxide, pharmaceuticals and pesticides, etc. It can also be used to produce diisopropyl ketone, isopropyl acetate and Thymol and gasoline additives.

As a solvent, it is a relatively cheap solvent in industry. It has a wide range of uses. It can be freely mixed with water. It has stronger solubility for lipophilic substances than ethanol. It can be used as nitrocellulose, rubber, paint, shellac, alkaloids, etc. solvent. It can be used to produce coatings, inks, extraction agents, aerosol agents, etc. It can also be used as antifreeze, detergent, additive for blending gasoline, dispersant for pigment production, fixative for printing and dyeing industry, anti-fogging agent for glass and transparent plastic, etc. Used as a diluent for adhesives, antifreeze, dehydrating agent, etc.

As chromatographic analysis standards, measure barium, calcium, copper, magnesium, nickel, potassium, sodium, strontium, nitrite, cobalt, etc. Used as a defoaming agent for water-based fracturing fluids in oil wells, air forms an explosive mixture that can cause combustion and explosion when exposed to open flames or high heat, and can react strongly with oxidants. In the electronics industry, it can be used as a cleaning and degreasing agent. In the oil and fat industry, cottonseed oil extractant can also be used for degreasing animal-derived tissue membranes.

Methoxyisopropyl alcohol

It is produced by reacting 1,2-propylene oxide and methanol in the presence of a catalyst, and then crude distilling and rectifying the reactants. Mainly used as solvent, dispersant and diluent, also used as fuel antifreeze, extraction agent, etc. Used as a solvent for nitrocellulose, a compounding agent for brake oil and detergents, etc. Widely used in coatings and cleaners. Specific applications: Reactive solvent for water-based coatings; Reactive solvent and coupling agent for solvent-based printing inks; Solvent for ballpoint pens and fountain pens; Coupling agent and solvent for household and industrial cleaners, rust removers and hard surface cleaners; Agriculture Solvent for insecticides; used in glass cleaner formulations when mixed with propylene glycol n-butyl ether.

Both compounds belong to alcohols and can be used as solvents in organic chemical synthesis. There is no particularly obvious difference between the two, especially in the first off application. Both isopropyl alcohol and methoxyisopropyl alcohol can be used as antifreeze, cleaners, additives for blending gasoline, dispersants for pigment production, fixatives in the printing and dyeing industry, and anti-fogging agents for glass and transparent plastics. The two compounds are roughly the same in some applications, and there are not many differences.
