Product Description

Product Description

Industry Grade Extractant N N-Dimethylformamide (DMF) 99.9% CAS68-12-2
       Dimethyl Formamide (DMF) is a colorless and transparent liquid, which is miscible with water and most organic solvents. Pure dimethylformamide has a special odor, and industrial grade or deteriorated dimethylformamide has a fishy smell because it contains impurities of dimethylamine. The source of the name is that it is the dimethyl substituent of formamide (the amide of formic acid), and both methyl groups are located on the N (nitrogen) atom. It is a common solvent for chemical reactions. As a polar (hydrophilic) aprotic solvent with a high boiling point, it can promote the SN₂ reaction mechanism. Dimethylformamide is manufactured using methyl formate and dimethylamine.
      Dimethylformamide also has a catalytic effect, which reduces the reaction temperature and improves the purity of the product. Although it is a "universal solvent".

Application

Dimethylformamide (DMF) is an important chemical raw material and a solvent with excellent performance. It is also an important intermediate in organic synthesis.
Mainly used in polyurethane, acrylic fiber, medicine, pesticides, dyes, electronics and other industries.
In the polyurethane industry as a washing curing agent, mainly used in the production of wet synthetic leather;
In the pharmaceutical industry as a synthetic drug intermediates, widely used in the production of doxycycline, cortisone, sulfonamides;
In the pesticide industry for the synthesis of high efficiency and low toxicity pesticide insecticides;
As a solvent in acrylic fiber industry, it is mainly used in dry spinning production of acrylic fiber. In the dye industry as a dye solvent;
In the electronics industry as tinned parts hardening and circuit board cleaning;
Other industries include carriers of dangerous gases, solvents for pharmaceutical crystallization, adhesives, etc.
