Polyol ester lubricant is an environment-friendly and energy-saving lubricant, which is widely used

In recent years, the country has gradually strengthened the remediation of environmental protection. It is not difficult to find the common development concept of environmental protection and energy conservation from the development strategy of multinational lubricant brands. The "green lubrication" element has been gradually introduced into the famous Chinese brands Great Wall and Kunlun.

Toxicity and application of high-purity iodomethane

Toxicity and application of high-purity iodomethane

Iodomethane is often used as the raw material for the production of drugs and fire extinguishing agents such as iodomethyl methionine (vitamin U), analgesics, antidotes, as well as the synthetic raw material of other organic compounds. It can also be used as a methylation reagent for the inspection of pyridine and microscope, and also as a fumigation disinfectant. In agricultural production, it is used as fungicide, plant parasitic nematode killer, soil pathogen killer, pre-sowing insecticide and herbicide. High-purity methyl iodide is often used in the pharmaceutical industry as an intermediate in organic synthesis. It is often used in the methylation reaction of alcohol, phenol, ketone, ester, carboxylic acid, amino compound, cyano compound, nitroalkane, sulfone, sulfoxide, imine and hydrazone; Iodomethane

Use of triethyl phosphate and precautions for transportation

Use of triethyl phosphate and precautions for transportation

Triethyl phosphate is a colorless transparent liquid with a slightly fruity taste and is easily soluble in water, ethanol, ether benzene and other organic solvents. Triethyl phosphate is stable at room temperature and hydrolyzes slowly when heated. It is a high boiling point solvent, often used as a plasticizer for rubber and plastics, and is also a raw material for preparing pesticides.

Introduction to the properties of high-purity methyl iodide

Introduction to the properties of high-purity methyl iodide

Methyl iodide, also known as methyl iodide, is a halogenated methane (methyl chloride, methyl bromide, methyl iodide) compound, which is often used in the pharmaceutical industry as an intermediate in organic synthesis. Because iodine ion is a good leaving group, high-purity iodomethane is a very good methylation reagent, which is often used in the methylation reaction of alcohol, phenol, ketone, ester, carboxylic acid, amino compound, cyano compound, nitroalkane, sulfone, sulfoxide, imine and hydrazone.

Analysis of the important role of triethyl phosphate in life activities

Analysis of the important role of triethyl phosphate in life activities

Today, I would like to share with you a classic article published in Science magazine in 1987, "Why Nature Chooses Phosphates". The author is Frank Henry Westheimer, a former chemistry professor at Harvard University, who died in 2007. This article mainly discusses the important role and uniqueness of triethyl phosphate in life activities

Emergency treatment and protection measures for leakage of high-purity methyl iodide

Emergency treatment and protection measures for leakage of high-purity methyl iodide

In case of leakage of high-purity methyl iodide, it is necessary to quickly evacuate personnel from the contaminated area to a safe area, immediately isolate them for 150 meters, and strictly restrict access. Cut off the ignition source. It is recommended that emergency response personnel wear self-contained positive pressure respirators and protective clothing. Do not contact the leakage directly. Cut off the source of leakage as much as possible to prevent it from entering the confined space such as sewer and spillway. A small amount of high-purity iodomethane leaked: mixed with sand or dry lime or soda ash. Large amount of leakage: build a dam or dig a pit for storage. Cover with foam to reduce steam disaster. Use explosion-proof pump to transfer to tank car or special collector for recycling or transport to waste disposal site
