Study on reaction of acetals between benzaldehyde and glycol
The synthetic conditions of benzaldehyde and glycol acetals by 732#strong acidic ion exchange resin are studied. The optimal synthetic conditions are molar ratio of benzaldehyde and glycol 1:1.75, dosage of benzene and activator 40mL and 1.5g respectively, reaction time for 90 minutes. The separating catalyzer and product by decompression filtration and decompression distillation are adopted in back disposal of the product.
