Usage

General Description

1,3-Dichloro-2,2-dimethoxypropane is a chemical compound with the molecular formula C5H10Cl2O2. It is commonly used in organic synthesis as a reagent for the protection of alcohols to form acetals. It is a colorless liquid with a chloroform-like odor and is insoluble in water but soluble in organic solvents. It is flammable and may form explosive peroxides upon exposure to air. Due to its potentially hazardous nature, it should be handled with care and stored in a cool, dry place away from heat and open flames. Additionally, it is important to wear appropriate protective gear when working with this chemical.

Preparing method for 1,1,3-trichloroacetone

The invention relates to a preparing method for 1,1,3-trichloroacetone. The preparing method comprises the following process steps that firstly, acetone and methyl alcohol serve as raw materials, an intermediate product 1,3-dichloroacetone dimethyl carbinol is obtained through chlorine chlorination preparation, a crude 1,1,3-trichloroacetone product is obtained through methyl alcohol stripping and deep chlorination, and a pure product is obtained through rectification. According to an improvement of the preparing mehtod, 1,3-dichloroacetone dimethyl carbinol easy to separate is prepared firstly from acetone, by-products 1,1-dichloroacetone and 1,1,1-trichloroacetone are separated out, then carbonyl is reduced through the method of introducing chlorine, new substances cannot be introduced, the purity of the end product1,1,3-trichloroacetone is high, and the total yield through the three-step reaction is high.

Chlorination of Aliphatic Ketones in Methanol

The chlorination of aliphatic ketones in methanol has been examined.The product distributions in methanol differ substantially from those obtained by chlorination in carbon tetrachloride.The reaction in methanol favors addition of chlorine to the least substituted carbon α to the carbonyl group.The effect is especially pronounced if an α carbon bearing two substituents is present.The distribution of products is determined by the relative stability of the enol ethers formed from the ketone under the reaction conditions.

Process for the preparation of selectively halogenated ketals

A method is disclosed wherein selectively halogenated ketals, and ultimately, halogenated ketones are prepared by treating secondary alcohols or halohydrins with halogen in an organic solvent under conditions of ordinary temperature and pressure. This method obviates the need for extreme times, temperatures and complex equipment while resulting in higher yields than obtained heretofore.
