METHOD OF PRODUCING ALKYD RESINS

摘要

FIELD: chemistry. ^ SUBSTANCE: present invention relates to a method of producing alkyde resins and can be used to produce polymer compounds, particularly high-quality bitumen. The method of producing alkyde resins involves reaction of a mixture of organic acids with a polyatomic alcohol at 160-180C and molar ratio of mixture of organic acids to polyatomic alcohol equal to 1:1-2 until achieving acid number 5-50 mg KOH/g in the reaction mixture. The mixture of organic acids contains 80-87 wt % terephthalic acid, 8-15 wt % p-toluic acid, up to 0.4 wt % benzoic acid, up to 0.1 wt % carboxybenzaldehyde and water - the balance. ^ EFFECT: simple process of producing alkyde resins and low power consumption. ^ 2 cl, 1 tbl, 3 ex
