Product Desciption

DESCRIPTION

Carbofuran is used in the control of more than 10 kinds of pests such as rust ticks, aphids, thrips, leafhoppers and other pests on fruit trees, cotton, vegetables, grain, and various other economic crops.

This product is a derivative of carbofuran, which has the same insecticidal activity as carbofuran .But its toxicity is much lower than carbofuran, a stomach insecticide .It can be metabolized into carbofuran in the organism and then play its effect to kill the insect. It has excellent control effect on the potato green peach aphid, black beetle, high dyed blind fly, cutworm and other insects. In addition, it can also better control cotton spider mite, billbug, tribolium confusum and spodoptera moth etc.
Carbamate insecticides, acaridants and nematides with high absorbability and broad-spectrum properties. It is a low toxic variety of Carbosulfan for the control of citrus, fruit trees, cotton and rice crops of aphids, mites, wireworm, beet and potato beetles, a hidden food tea leafhopper, Grapholitha molesta, codling moth and other pests. The administration concentration is 5mg/L and the effective component is 6.8 ~ 15g /100m2.

PREPARATION METHODS

Method 1:
Preparation of two n-butanamine sulphide Add two n-butyl amine and petroleum ether (60~90ºC ), mixing and cooling to 0ºC . Then slowly drip disulfur dichloride and maintain the temperature at 0~10 ºC. Afterwards, the reaction will be maintained at a constant temperature. The proportioning of the di-n-butylamine, disulfur dichloride and sulfuric chloride is 1:0.6:0.55(mol). The yield is 88%.
The synthesis of carbosulfan Two n-butanamine sulphur chloride reacts with carbosulfan with the ratio of 1:1. The reaction process is added with a proper amount of alkaline solution, and the reaction temperature is 10~20 ºC. The reaction time period is 2h. Add water and mix it for 10 minutes after the reaction. Filter it and the unreacted is carbosulfan which can be reused. The filtrate is stratified and the oil layer is decompressed and dissolving, and the yield is 90%.

Method 2:
The synthesis of the intermediates hydroxyl compounds can be take the carbosulfan as reference. There are also literature reporting that starting from cyclohexanone and isobutyrate, five steps will be able to get it synthesized through condensation, chlorination, aromatization, hydrolysis and closed loop reaction. It is characterized by the synthesis of non aromatic compounds and is a highly selective synthesis route.
