Chemical structure

Production

One of method for preparing 3-methoxy propylamine by using 3-methoxy propanol as a raw material and Cu-Co/Al2O3-diatomite as a catalyst.

1. At certain pressure and certain temperature, the 3-methoxy propanol is driven into a preheater and then it is mixed with ammonia gas and hydrogen;
2. the mixture is preheated and vaporized and enters a fixed-bed reactor for reaction
3. the material after reaction is subjected to condensation and cooling, the gas and the liquid are separated,
4. 3-methoxy propylamine is produced as a product

Reactions

mops reacts with bis (2-carbamoylphenyl) disulfides to produce substances which are used in limiting the growth of mildew fungi in alkyd and latex paints.

It reacts with carbamates, quinones, and benzothiazole to produce other products with similar function. It can react with styrene-maleic anhydride copolymer and a diamine to produce compounds which could prove to be effective against silicosis. Such specialized applications have been propelling growth for the global methoxy propylamine market.

Applications

3-Methoxy propylamine is commonly used in the water treatment industry as a flocculating agent. It is also used to prevent corrosion in condensate systems and can reduce carbon dioxide in water.

it is a kind of pesticide herbicide midbody and pharmaceutical-chemical intermediate and basic organic chemical manufacturing, Fabricated metal product manufacturing, Oil and gas drilling, extraction, and support activities, Textiles, apparel, and leather, water-based paints and floor and fabric finishes.

In water treatment industries MOPA reacts with acrylonitrile polymers to produce polyelectrolytes, which are soluble in water and hence, find applications as flocculating agents.

This substance is used in the production of amino soaps. These soaps are used for the production of synthetic and natural resins and dispersions and wax emulsions.

MOPA is also used as an organic intermediate, emulsifier in anionic coatings and wax formulations.
