Organic Solvent

This product is sensitive to light. When exposed to light, it reacts with oxygen in the air and gradually decomposes into highly toxic phosgene (carbonyl chloride) and hydrogen chloride. Narcotic. There is a possibility of cancer.

Dimethylformamide is a good organic solvent and widely used. In petrochemical industry, dimethylformamide can be used as gas absorbent to separate and refine gas. As a washing and curing agent in polyurethane industry, it is mainly used in wet synthetic leather production; As a solvent in acrylic fiber industry, it is mainly used in dry spinning production of acrylic fiber; In the electronic industry as tinning parts of quenching and circuit board cleaning, etc; Other industries include carriers of dangerous gases, solvents for drug crystallization, adhesives, etc. In organic reactions, dimethylformamide is not only widely used as a solvent, but also an important intermediate in organic synthesis. It can be used to produce Chlordimeform in pesticide industry; In the pharmaceutical industry, it can be used for the synthesis of iodamine pyrimidine, doxycycline, cortisone, vitamin B6, iodoside, qupinjing, thiadiazine, n-formylsarcoma lysin, antineoplastic acid, methoxyaryl mustard, benazepril, cyclohexylnitrosourea, furafluorouracil, hemostatic acid, betamethasone, megestrol, danvita, chlorphenamine and sulfonamides. Dimethylformamide plays a catalytic role in hydrogenation, dehydrogenation, dehydration and dehydrohalogenation, which reduces the reaction temperature and improves the purity of the product.

This product is mainly used as a plasticizer for plastic products. It is non-toxic and has good compatibility.

Tetramethylammonium chloride is a phase transfer catalyst in organic synthesis. Its catalytic activity is stronger than that of triphenylphosphorus and triethylamine. It is a white crystalline powder at room temperature. It is volatile, irritating, easy to absorb moisture, soluble in methanol, water and hot ethanol, insoluble in ether and chloroform. When heated above 230 ℃, it is decomposed into trimethylamine and methyl chloride. Median lethal dose (mice, abdominal cavity) 25mg / kg. It is also used in the synthesis of liquid crystalline epoxy compounds, polarographic and pop analysis, electronic industry, etc.

Triphenyl phosphine oxide is an organic phosphorus compound. It is white crystal at room temperature. It is the oxidation product of triphenylphosphine. It is often used as organic synthesis intermediate, pharmaceutical intermediate, catalyst and extractant.
