Description
Изобретение относитс к области получени амидов жирных кислот, -которые наход т широкое применение в народном хоз йстве.The invention relates to the field of production of fatty acid amides, which are widely used in traditional households.
Известен способ получени амидов жирных кислот путем обработки -соответствующей кислоты аммиаком в присутствии катализатора- алюминатной окиси алюмини при 180-190°С н под давлением кг/см.A known method for producing fatty acid amides by treating the corresponding acid with ammonia in the presence of an aluminate alumina catalyst at 180-190 ° C under a pressure of kg / cm.
Недостатками способа вл ютс низкий выход целевого продукта (60-65%) и сложность технологического процесса, св занна с проведением процесса при высоком давлении (50 кг/см) и повышенной температуре.The disadvantages of the method are the low yield of the target product (60-65%) and the complexity of the technological process associated with carrying out the process at high pressure (50 kg / cm) and elevated temperature.
С целью упрощени технологического процесса и повышени выхода целевого п родукта предлагаетс анилид дистиллированной соапсточной жирной кислоты обрабатывать водным раствором аммиака при 25-30° С.In order to simplify the process and increase the yield of the target product, it is proposed to treat the anilide distilled soapstochnoy fatty acid with an aqueous solution of ammonia at 25-30 ° C.
Предлагаемый способ позвол ет получать целевой продукт с выходом 90%.The proposed method allows to obtain the desired product with a yield of 90%.
Пример. 100 г анилида дистиллированных соапсточных жирных -кислот помещают в реактор и при перемешивании добавл ют 16 мл 25%-ной гидроокиси аммони . Реакп;ию переамидировани осуществл ют При 25- 30° С в течение 2 час.Example. 100 g of anilide distilled co-effluent fatty β-acids are placed in a reactor and 16 ml of 25% ammonium hydroxide are added with stirring. The reaction of re-amidation is carried out at 25-30 ° C for 2 hours.
Проведенный ИК-спектральный анализ полученного продукта показывает наличие С О 1720 CM-S С-N 1650 см-, N-Н 1700 см- группы.The carried out IR-spectral analysis of the obtained product shows the presence of С О 1720 CM-S С-N 1650 cm-, N-Н 1700 cm- group.

Полученный продукт при 20--22° С раствор етс в серном эфире и хлороформе и не раствор етс в дистиллированной воде.The resulting product is dissolved at 20--22 ° C in sulfuric ether and chloroform and not soluble in distilled water.
При 40° С амид дистиллированных соапсточных жврных кислот растворим в этаноле и метаноле.At 40 ° C, the amide of distilled acidic acid is soluble in ethanol and methanol.
Предмет изобретени Subject invention
Способ получени амидов жирных кислот с применением аммиака при нагревании с последующим выделением,целевого продукта известным приемом, отличаюш.ийс тем, ЧТО, с целью упрощени технологического процесса и повышени выхода целевого продукта, анилид дистиллированной соапсточной жирной кислоты обрабатывают водным раствором аммиака при 25-30° С.The method of producing fatty acid amides using ammonia by heating and then isolating the target product by a known technique, which is different from THAT, in order to simplify the process and increase the yield of the target product, anilide is distilled with coptic acid fatty acid with an aqueous solution of ammonia at 25-30 ° C.
