Abstract

FIELD: chemical technology. SUBSTANCE: method involves interaction of colophony, polyhydric alcohol and disproportioning agent at heating. Interaction is carried out in the presence of resol alkylphenolformaldehyde resin (2-6% of the parent colophony mass). Sulfur-containing alkylphenolformaldehyde resin "Octofor S" (0.05-0.50% of colopholy and resin) is used as disproportioning and clearing agent. Polyhydric alcohol is used at amount 10.1-10.8% of the parent colophony mass. Interaction can be carried out in the presence of phosphoric acid. EFFECT: increased softening point of colophony esters.

Сущность изобретения: в способе получения модифицированного эфира канифоли путем взаимодействия канифоли, многоатомного спирта и диспропорционирующего агента при нагревании взаимодействие проводят в присутствии резольной алкилфенолформальдегидной смолы в количестве 2 - 6% от массы исходной канифоли, а в качестве диспропорционирующего, выполняющего одновременно функцию осветляющего агента, используют серусодержащую алкилфенолформальдегидную смолу "Октофор S" в количестве 0,05 - 0,50% от массы смеси канифоли и смолы. При этом многоатомный спирт используют в количестве 10,1-10,8 от массы исходной канифоли. Возможно проведение взаимодействия в присутствии фосфорной кислоты. Предлагаемый способ позволяет повысить температуру размягчения эфиров канифоли.The inventive method for producing a modified rosin ester by reacting rosin, polyhydric alcohol and a disproportionate agent when heated, the interaction is carried out in the presence of rezol alkylphenol-formaldehyde resin in an amount of 2-6% by weight of the original rosin, and use as a disproportionate, simultaneously performing the function of clarifying agent, "Octophor S" sulfur-containing alkyl phenol-formaldehyde resin in an amount of 0.05 - 0.50% by weight of a mixture of rosin and resin. In this case, polyhydric alcohol is used in an amount of 10.1-10.8 by weight of the initial rosin. Perhaps the interaction in the presence of phosphoric acid. The proposed method allows to increase the softening temperature of rosin esters.
