3 4-Dimethylbenzophenone（CAS# 2571-39-3)

Introduction

3,4-Dimethylbenzophenone, also known as ketocarbonate or Benzoin. The following is a description of its nature, use, preparation and safety information:

Nature:

-Appearance: 3,4-Dimethylbenzophenone is a white crystalline solid.

-Solubility: It is almost insoluble in water, and has high solubility in organic solvents such as ethanol and dimethylformamide.

-Melting point: The melting point of 3,4-dimethylbenzophenone is about 132-134 degrees Celsius.

-Chemical properties: It is an electrophilic reagent that can participate in various reactions such as hydrogen bond formation, oxidation-reduction reaction between ketone carbon and methyl.

Use:

- 3,4-Dimethyl benzophenone is mainly used as a reagent for organic synthesis reactions.

-It can be used as an electrophilic reagent to participate in electrophilic addition reactions, ketone carbonate formation and other reactions.

-It can also be used as a photosensitizer for lithography, light curing and other fields.

Preparation Method:

One method for the preparation of -3,4-dimethyl benzophenone is the synthesis reaction of barone. The steps of the reaction are as follows: First, styrene is reacted with excess bromine under light or ultraviolet light to form β-bromostyrene. The β-bromostyrene is then reacted with a hydroxide (e. g., NaOH) to form 3,4-dimethylbenzophenone.

-Another preparation method is to react acetophenone and sodium bromide under alkaline conditions to generate 3,4-dimethyl benzophenone.

Safety Information:

- 3,4-Dimethylbenzophenone is less toxic.

-Avoid skin contact and inhalation when using.

-Ruyi external contact to the skin, should immediately rinse with plenty of water.

-If inhaled, move immediately to a well-ventilated place.

-It is recommended to wear appropriate protective gloves and breathing apparatus during operation.

-When using and storing, please follow the safe operating procedures and place it out of the reach of children.
