12542-85-7 - Introduction
Aluminum sesqui methyl chloride is a kind of organic aluminum compound, chemical formula is (CH3)2AlCl, colorless liquid at room temperature. It has some of the following properties:
1. Strong pungent odor;
2. Soluble in many organic solvents, such as ethanol, acetone, etc;
3. It can react with water to generate intense heat, generating hydrogen chloride gas and alumina;
4. easy to decompose in the air.
semi-methyl aluminum chloride in the chemical industry has a wide range of applications, common uses are:
1. as a catalyst: in organic synthesis reactions, aluminum sesqui-methyl chloride is often used as a catalyst for acylation, alkyd condensation, amidation, alkyne anchoring and other reactions;
2. as the initiator of polymerization reaction: sesqui-methyl aluminum chloride is often used to initiate Latin polymerization, gore calixamide polymerization and other reactions;
3. as a swelling agent: aluminum sesqui-methyl chloride swellable polymer, the pore properties of the polymer were detected;
4. as a prepolymer of high temperature sealing material: sesqui-methyl aluminum chloride can be used as a prepolymer of synthetic fluorocarbon polymer.
the preparation method of semi methyl aluminum chloride is generally obtained by the reaction of aluminum carbonate and hydrochloric acid, and the specific preparation process is as follows:
Add aluminum carbonate dropwise into the reaction vessel with an appropriate amount of hydrochloric acid solution, while controlling the reaction temperature at 25-30 degrees Celsius. After the reaction has ended, the solution is neutralized with concentrated sodium hydroxide solution and the sesquimethylaluminum chloride is then separated off.
in the use of semi methyl aluminum chloride need to pay attention to safety matters:
1. Wear protective gloves, goggles and other personal protective equipment when using semi-methyl aluminum chloride;
2. Avoid contact with skin, eyes and respiratory tract. If you accidentally come into contact with skin, you should wash it with plenty of water immediately;
3. try to avoid contact with water, if splashed into the water, should immediately leave the splash area, and keep a safe distance;
4. in the storage and processing of aluminum sesquimethyl chloride, to stay away from the fire and oxidant, to prevent its contact with combustible substances;
5. in the operation of the semi methyl aluminum chloride, should be operated in a well ventilated environment, in order to reduce the risk of volatile and inhalation.
