Paragraph 0016; 0043-0044; 0062-0064, (2022/01/05)
The invention relates to the field of chemical engineering, and relates to an organic tin catalyst, in particular to stannous salicylate and application in preparation of polyurethane foam. According to the invention, a synthesis method of aminosalicylic acid and alkyl salicylic acid containing long alkyl chains, and then the aminosalicylic acid and alkyl salicylic acid are used as raw materials to react with stannous oxide to generate stannous salicylate; ompared with traditional stannous carboxylate, only carboxyl in the traditional stannous carboxylate is coordinated with a tin center, and the hydroxyl and carboxyl in the stannous salicylate provided by the invention are coordinated with the tin center at the same time, so that the coordination compound is more stable and higher in catalytic activity; and the method for synthesizing the long alkyl chain aminosalicylic acid is not reported in public literatures, and the method is cheap in reagent, simpler in formula, more convenient to operate, green, safe, efficient, environmentally friendly and suitable for industrial production.
