Pesticide production includes three parts: intermediate, API and preparation. Intermediate is the key product of the process before making API, and can become a material of API after further molecular change or refining. The content of API is generally more than 95%, and it is a main raw material for preparation production. The efficacy of API is poor when used directly, and it is generally sold to the preparation factory, which can improve the efficacy of API after it is made into a preparation. The effective content of the API in the preparation is generally about 20%, and the other groups are divided into emulsifiers, dispersants, wetting agents, etc., which are sold to end consumers after packaging and labeling. Pesticides are classified by use into three main sections: insecticides, herbicides and fungicides. Let's have a look at them respectively.
DMF is a good organic solvent and an important intermediate in organic synthesis with strong polarity and low toxicity. Among insecticides, DMF dosage is large varieties of imidacloprid, acetamiprid, fipronil and so on. The widespread use of pesticides, on the one hand, promotes the increase in the income of farmers increase and the rapid development of agriculture, on the other hand, synthetic organic pesticides toxic, the production process will produce a large amount of sewage, in use process will pollute the environment, so the organochlorine, organophosphorus and carbamate pesticides in organic synthesis because of do not conform to the requirements of environmental protection gradually withdraw from the market, Low toxicity and non-toxicity is the development direction of pesticide industry. With the rise of biological drugs, dimethylformamide (DMF) as a solvent (a liquid that can dissolve gas, solid and liquid into a uniform mixture) has been widely used in the preparation of bulk drugs and pharmaceutical intermediates, which conforms to the requirements of The Times.
Herbicides are agents that kill weeds completely or selectively. According to the mode of action can be divided into :(1) selective herbicide: this agent can kill weeds, and harmless to seedlings. Such as cover grass can, pucao net, fruit, etc. (2) Herbicide: herbicide is toxic to all plants, as long as contact with the green part, regardless of seedlings and weeds, will be injured or killed. It is mainly used in the main and secondary roads of the nursery before sowing, after sowing, before emergence. Such as glyphosate.
Fungicides are mainly divided into four categories: protective fungicide, eradication fungicide, therapeutic fungicide, disease-resistant activator, respectively to protect crops, kill pathogens, enhance the role of crop resistance.
DMF was applied in all three plates, of which the amount of pesticide was large and the amount of herbicide was small, accounting for about 90%, and the amount of fungicide was negligible. Among the downstream industries of DMF, the overall market share of pesticides is only about 5%, but it often becomes a key minority that affects the market trend of DMF in the dull period, which is worth paying close attention.
Yuanfar company has been engaged in the export of DMF in China for a long time. It has cooperated with many enterprises including Hualu Hengsheng and Luxi Chemical, and is your trustworthy partner.
