Pesticide Intermediates

Quinoline is a heterocyclic aromatic organic compound with strong odor and colorless hygroscopic liquid. When quinoline is exposed to light, it gradually turns pale yellow and further turns brown. Quinoline is slightly soluble in water, but easily soluble in many organic solvents. Quinoline is an important intermediate in metallurgy, dyestuff, polymer and agrochemical industry. Quinoline is toxic. Exposure to quinoline vapor for a short period of time may cause corrosion of nose, eyes and respiratory tract. It may also cause dizziness and nausea. Quinoline is currently used in the pharmaceutical industry to produce nicotinic acid and 8-hydroxyquinoline drugs; It is used in printing and dyeing industry to produce cyanine blue pigment and photosensitive pigment; Rubber industry is used to make accelerator; In agriculture, it is used to produce 8-hydroxyquinoline copper and other pesticides. Quinoline is also an important organic synthesis reagent, basic condensation agent and solvent. It can also be used as disinfectant, preservative and solvent.

This product is widely used as feed and food antioxidant. Spraying this product on dehydrated feed or pre harvest feed crops can prevent fat and protein feed from spoiling during storage. It can be used for the preservation of drugs such as vitamin A and vitamin E. Prevent the formation of organic peroxides in canned meat food and animal feed. Improve the intake of vitamin E in chicks and maintain it at a normal level. Improve carcass quality and increase animal weight. The product can also be used for the preservation of apples, pears and other fruits; It is reported that ethoxyquine is an effective protective agent to prevent rubber grass poisoning in sheep. This product is also a polluting rubber antioxidant (antioxidant aw), which is mainly used for natural rubber and synthetic rubber, especially styrene butadiene rubber. Superior oxygen resistance and ozone resistance, weather resistance, heat resistance K and flexion cracking resistance. The general dosage is 1-2 parts, sometimes it can be increased to 3-4 parts. It has synergistic effect with 4010NA and paraffin, which can further improve the protection efficiency. It is not easy to spray cream, but it is highly polluting, and is not suitable for light and bright products. The product is used for apples and pears and can prevent and treat Apple tiger skin disease. The oral LD50 of rats was 3150 mg / kg and that of mice was 3000 mg / kg.
