Solvent

Solvent oil is one of the five categories of petroleum products. Solvent oil is widely used. The largest amount of paint solvent oil (commonly known as paint solvent oil), followed by edible oil, printing ink, leather, pesticides, pesticides, rubber, cosmetics, spices, medicine, electronic components and other solvent oils. About 400-500 kinds of solvents are sold on the market, of which solvent oil (hydrocarbon solvents and benzene compounds) accounts for about half. Solvent oil is a complex mixture of hydrocarbons, which is very easy to burn and explode. Therefore, from production, storage and transportation to use, we must pay strict attention to prevent fire.

Light aromatic solvent oil is a chemical with a density of 0.96-0.99. Emulsifiable concentrate is the most basic and important formulation of pesticide formulation products. It has been welcomed by users for a long time and has occupied the first place in the pesticide sales market. In 2014, the registration of emulsifiable concentrate products accounted for about 33%.

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.
