Изобретение относится к области органической химии, а именно - к способу получения бензилдиметилацеталя формулы
Figure 00000001

который может быть использован в качестве фотоинициатора полимеризации. С целью упрощения технологии процесса, сокращения времени процесса бензилдиметилацеталь получают взаимодействием дифенилдикетона с диметоксиметаном в присутствии пятихлористого фосфора при соотношении реагентов дифенилдикетон: диметоксиметан:пятихлористый фосфор = 1 : 60 : 1 при комнатной температуре в течение 20 - 25 мин.The invention relates to the field of organic chemistry, namely to a method for producing benzyldimethylacetal formula
Figure 00000001

which can be used as a polymerization photoinitiator. In order to simplify the process, reducing the time of the process, benzyldimethylacetal is obtained by reacting diphenyl dicetone with dimethoxymethane in the presence of phosphorus pentachloride with a ratio of diphenyldicetone: dimethoxymethane: phosphorus pentachloride reagents = 1: 60: 1 at room temperature for 20 to 25 minutes.
