Reaction Steps

To a mixture of 24.2 parts of 5-α-methylbenzylsalicylic acid, 21.2 parts of o-xylene, 8.9 parts of 37% formalin and 25 parts of acetic acid was added 4.0 parts of 95% sulfuric acid (catalyst). After being heated under reflux for 5 hours, the reaction mixture was washed with water, and unreacted o-xylene and water were removed by vacuum distillation to give 35 parts of 5-α-methylbenzylsalicylic acid-o-xylene-formaldehyde co-condensation product. 10 parts of the co-condensation product was converted into its tin salt in a similar manner as in Synthesis Example 3. There was obtained 13 parts of tin salt of 5-α-methylbenzylsalicylic acid-o-xylene-formaldehyde co-condensation product.
