Octadecylmagnesium chloride - Introduction
Octadecylmagnesium chloride(Octadecylmagnesium chloride) is an organometallic compound with the chemical formula C18H37ClMg. The following is a description of its nature, use, preparation and safety information:
1. nature:
-Appearance: White solid
-Solubility: Soluble in benzene, toluene and other organic solvents, insoluble in water
-melting point: about 290-300 ℃
-Molecular weight: about 380.07g/mol
2. use:
- Octadecylmagnesium chloride are often used as Grignard reagents in organic synthesis, and can react with aldehydes, ketones and other electrophilic reagents to produce alkyl magnesium reagents (Grignard reagents), thus carrying out various organic synthesis reactions.
-It can also be used as a surfactant, dye dispersant, oil industry catalyst and other applications.
3. preparation method:
The preparation of Octadecylmagnesium chloride is usually carried out by Grignard reaction. The octadecyl bromide is reacted with metal magnesium in an inert atmosphere (such as nitrogen) to generate an octadecyl magnesium reagent, and then a reagent such as cuprous chloride is added to perform a subsequent reaction to obtain a Octadecylmagnesium chloride.
4. Safety Information:
- Octadecylmagnesium chloride are organometallic compounds and have certain toxicity. Direct contact with skin and inhalation of dust should be avoided.
-Use appropriate protective equipment such as protective gloves, goggles, etc. during handling and storage.
-It should be operated in a well-ventilated place to avoid excessive vapor concentration.
-Waste should be disposed of in accordance with local regulations.
Please note that organometallic compounds often pose certain risks to humans and the environment. Relevant safety data should be carefully read before use and correct operating procedures should be followed.
