Description
Известен способ получени воска, заключающийс в этерификации природных кислот спиртами в присутствии серной кислоты при 100-110°С.A known method for producing wax involves esterifying natural acids with alcohols in the presence of sulfuric acid at 100-110 ° C.
предложенный способ получени воска отличаетс от известного тем, что в качестве исходного сырь примен ют синтетические высокомолекул рные или кубовые жирные кислоты . Способ расшир ет сырьевую базу производства воска, при этом используют высокомолекул рные жирные кислоты, вл ющиес отходом производства, что снижает стоимость конечного продукта.The proposed method for producing wax differs from the known one in that synthetic high molecular weight or bottom fatty acids are used as the raw material. The method expands the raw material base of wax production, using high molecular weight fatty acids, which are waste products, which reduces the cost of the final product.
Способ осуществл ют следуюн1,им образом.The method is carried out in the following manner.
Эквимолекул рное количество кислот и спиртов с некоторым избытком одного из компонентов (5-10о/о) постепенно нагревают до 250°С в вакууме в течение 2-6 час. Полученныи продукт, вл ющийс синтетическим воском , характеризуетс следующими показател ми:An equimolecular amount of acids and alcohols with a certain excess of one of the components (5-10 o / o) is gradually heated to 250 ° C under vacuum for 2-6 hours. The resulting product, which is a synthetic wax, is characterized by the following indicators:
Температура застывани в С50-60Pour point in С50-60
Кислотное число в мг КОН/г5-20Acid number in mg KOH / g5-20
Число омылени в мг КОН/г70-100Saponification number in mg KOH / g70-100
Эфирное число в мг КОН/г65-85Essential number in mg KOH / g65-85

Предмет изобретени Subject invention
Способ получени воска путем реакции этерификации , отличающийс тем, что, с целью сни кени стоимости конечного продукта и расширени сырьевой базы, в качестве исходного сырь используют синтетические высокомолекул рные или кубовые жирные кислоты.A method of producing wax by an esterification reaction, characterized in that, in order to reduce the cost of the final product and expand the raw material base, synthetic high molecular weight or bottom fatty acids are used as a raw material.
