What is 2-Methyl-3-Butyn-2-ol?
3-Methylbutylene-3, also known as 2-methyl-3-butylene-2-ol, is one of the important alkyne alcohols, mainly used in corrosion inhibitors, food and medicine, other chemical products and other fields. In the application of corrosion inhibitor, 2-methyl-3-butyne-2-ol has both polar and non-polar groups in its molecule, so it can be used as an adsorptive corrosion inhibitor and can effectively prevent metal hydrogen embrittlement.
3-Methylbutynol is an alcohol. Alcohols integrate with alkali steels, nitrides and also solid minimizing agents to generate flammable and/or poisonous gases. They react with oxyacids as well as carboxylic acids to form ester and water. Oxidants transform them right into aldehydes or ketones. Alcohols show weak acid and also weak base actions. They can start polymerization of isocyanates and also epoxides.
2-Methyl-3-butyn-2-ol is used as an intermediate in the manufacture of agricultural chemicals and special chemicals.
It is used as an intermediate for synthetic medicine and pesticide, terpene flavor intermediate, acid corrosion inhibitor, viscosity stabilizer, viscosity reducer, polishing agent for nickel or copper plating, chlorinated hydrocarbon stabilizer, etc.
3-Methyl butynol can likewise be utilized as polymerization prevention for platinum catalyzed hydrosilylation reaction in silicone rubber.

Preparation of 2-Methyl-3-Butyn-2-ol
Preparation of reaction solution
First, replace the 500L autoclave with ammonia gas three times, lower the temperature in the reactor to -20°C, add liquid ammonia (144.5Kg, 8500mol), start stirring, and feed acetylene (16800L, 750mol) at a concentration of 20wt%. Magnesium sulfate aqueous solution 43.5g and concentration are 50wt% potassium hydroxide aqueous solution (1008g, the potassium hydroxide consumption as solute is 3mol% of acetone), be warming up to 10 ℃ and add acetone (17.4Kg, 300mol), control acetone to add The feed rate is completed in about 1h; the reaction temperature is 10°C, after 2h of reaction, add 5Kg of 10wt% ammonium sulfate aqueous solution for neutralization, and obtain 1# reaction solution containing 3-methylbutynol-3, and take a sample The reaction solution was checked by GC.
The composition of 1# reaction solution: the content of inorganic salt is 2.16wt%, the content of water is 16.61wt%, the content of 3-methylbutynol-3 is 77.30wt%, the content of acetone is 3.56wt%, 2, The content of 5-dimethyl-3-hexyne-2,5-diol is 0.05wt%, and the content of other components is 0.32wt%, based on the total weight of the components of the 1# reaction solution as 100wt%.
