Noteworthy pesticide intermediates in fine chemicals

Versatate also known as acid and trialkyl acetic acid. It is a class of branched chain unsaturated carboxylic acid and an important branch of industrial fatty acids. The chemical properties of the tert-carbonic acid derivatives are also more stable, such as tert-carbonic acid esters with excellent hydrolysis resistance.

In addition, it has a higher heat resistance, weather resistance and color resistance. Because tert-carbonate series products have excellent physical and chemical properties, they are widely used in the pesticide industry. There are just some versatate manufacturers in China and the market demand is mainly dependent on imports. With the domestic research accelerated in recent years, now China has the industrial conditions.

Tert-carbonate series products widely used in pesticides, especially trimethyl acetic acid is the most common, trimethyl triphenyl bismuth acetic acid and acetone for the synthesis of the frequency that the ketone is very tight domestic pesticide intermediates, the frequency that ketones can be synthesized in a variety of new fungicides, plant growth regulators and insecticides. Triadimenol, benzyl chloride triadimenol, triadimefon, paclobutrazol, dual oxacillin alcohol affects trazodone, tebuconazole alcohol, suppressing bud yl, shrinkage strain l, trazodone, and these products have high efficiency, low toxicity, absorption, broad-spectrum with less residues and residues of a short advantage. Is expected to 2012 China pesticide industry consumed about Versatate the 1500t around, the total demand of the market is about 7500t.

Iminodiacetic acid has a wide range of applications in the pesticide industry for the synthesis of glyphosate. As an important organic intermediate, iminodiacetic acid in China has a relatively large space for development. Iminodiacetic acid is mainly used to produce herbicide glyphosate, glyphosate market demand in China growing in recent years, has shown strong sales momentum. Chinese manufacturers still commonly used by chloroacetic acid and alkyl ester method, which mainly due to China iminodiacetic acid production and higher prices, can not meet the requirements of the development of glyphosate industry. China each year iminodiacetic acid of the total demand of 20 tons or more. Thus, the iminodiacetic 10-hydroxydecanoic acid in China with good development and utilization prospects, the market prospect is broad.

Furan is more extensive use of heterocyclic compounds, furan derivatives, including single ring and fused ring compounds. Furan phenol catechol with isobutylaldehyde, for the synthesis of an important pesticide intermediates, mainly used for the synthesis of low toxicity and efficient carbamate insecticide carbofuran, carbosulfan. Especially with the domestic part of the highly toxic organophosphorus pesticides banned carbofuran market demand for the rapid increase in current annual production capacity of 4000t / a, but there are many areas of the project investment, the other of its synthesis The raw materials of catechol synthesis technology has been successfully developed and built 1000t / a level of industrial production equipment, furan phenol market development is very promising.

Indole is an important fine chemical raw materials widely used in the pesticide industry, its application have been enduring, and new applications are constantly being developed. In the pesticide, the indole with its unique chemical structure, make derivative pesticide has a unique physiological activity of many of the physiological activity of a strong natural substances are indole derivatives. Indole acetonitrile as a plant growth regulator use effect is 10 times the indole acetic acid can be used for root growth of tea and mulberry trees, only their goods in Japan, the amount of 2000t / a, very popular on the international market.

In recent years, synthetic raw materials of pesticides tend to choose the heterocyclic compounds. It is mainly because of the unique structure of heterocyclic compounds displaying a unique high physiological activity. It can meet the demand for new pesticides in biological evolution.
