Abstract
Description
Изобретение относится к сельскому хозяйству, конкретно к способам получения диацетата натрия, который может быть использован в качестве кормовой добавки сельскохозяйственным животным. The invention relates to agriculture, specifically to methods for producing sodium diacetate, which can be used as a feed additive for farm animals.
Диацетат натрия (натрий кислый уксуснокислый) используют как кормовую добавку коровам с целью повышения удоев и жирности молока [1], более эффективную чем ацетат натрия. Описан способ получения диацетата натрия взаимодействием тригидрата ацетата натрия с уксусной кислотой в среде этанола [2, 3]. Sodium diacetate (sodium acid acetic acid) is used as a feed additive to cows in order to increase milk yield and milk fat [1], which is more effective than sodium acetate. A method for producing sodium diacetate by the interaction of sodium acetate trihydrate with acetic acid in ethanol is described [2, 3].
Кормовую добавку на основе диацетат натрия получают и используют в виде моногидрата, белого кристаллического вещества, растворимого в воде в соотношении 1:1 [2, 4]. Sodium diacetate based feed additive is prepared and used as a monohydrate, a white crystalline substance, soluble in water in a ratio of 1: 1 [2, 4].
Недостатком способа являются высокие затраты на сырье (продажный тригидрат ацетата натрия и этанол). The disadvantage of this method is the high cost of raw materials (commercial sodium acetate trihydrate and ethanol).
Цель изобретения - снижение затрат при получении продукта. The purpose of the invention is to reduce the cost of obtaining the product.
Указанная цель достигается тем, что для получения кормовой добавки на основе диацетата натрия используют тригидрат ацетат натрия в виде побочного продукта (отхода) производства полиэфиров, например политетраметиленэфиргликоля. This goal is achieved by the fact that to obtain a feed additive based on sodium diacetate, sodium acetate trihydrate is used as a by-product (waste) of the production of polyesters, for example polytetramethylene ether glycol.
Побочный продукт содержит 94-98% основного вещества, в несколько раз дешевле продажного технического продукта. A by-product contains 94-98% of the main substance, several times cheaper than a commercial technical product.
Процесс проводят путем смешивания при комнатной температуре эквимольных количеств (1:1) тригидрата ацетата натрия, побочного продукта и уксусной кислоты, выдержки в течение 20-30 мин, нагрева до 60oС для полного растворения компонентов и последующих упаривания и сушки при температуре не более 65oС для удаления избытка воды.The process is carried out by mixing at room temperature equimolar amounts (1: 1) of sodium acetate trihydrate, a by-product and acetic acid, holding for 20-30 minutes, heating to 60 o C to completely dissolve the components and subsequent evaporation and drying at a temperature of not more than 65 o C to remove excess water.
После полного растворения процесс контролируют по значению рН (5-6). После упаривания и сушки до постоянной массы готовый продукт охлаждают в эксикаторе. Готовый продукт представляет собой белый кристаллический порошок, моногидрат диацетата натрия, растворим в воде при соотношении 1:1. After complete dissolution, the process is controlled by the pH value (5-6). After evaporation and drying to constant weight, the finished product is cooled in a desiccator. The finished product is a white crystalline powder, sodium diacetate monohydrate, soluble in water at a ratio of 1: 1.
Пример. В колбу вместимостью 50 мл вносят 14,4 г тригидрата ацетата натрия (побочного продукта), содержащего 96,6% основного вещества, постепенно добавляют 6 г уксусной кислоты, перемешивают, выдерживают 20 мин при комнатной температуре. Затем смесь нагревают на водяной бане при 60oС до полного растворения компонентов (рН смеси 5,5 по универсальной индикаторной бумаге), затем в чашке Петри упаривают и сушат в сушильном шкафу при температуре 60-65oС до постоянной массы, охлаждают в эксикаторе. Получают 15,9 г моногидрата диацетата натрия, белого кристаллического вещества, растворимого в воде в соотношении 1:1 (1 г в 1 мл воды).Example. 14.4 g of sodium acetate trihydrate (by-product) containing 96.6% of the basic substance are added to a 50 ml flask, 6 g of acetic acid are gradually added, stirred, incubated for 20 minutes at room temperature. Then the mixture is heated in a water bath at 60 o C until the components are completely dissolved (pH 5.5 of the mixture according to universal indicator paper), then evaporated in a Petri dish and dried in an oven at a temperature of 60-65 o C to constant weight, cooled in a desiccator . 15.9 g of sodium diacetate monohydrate, a white crystalline substance, soluble in water in the ratio 1: 1 (1 g in 1 ml of water) are obtained.
Таким образом, предложенный способ получения кормовой добавки на основе диацетата натрия позволяет снизить затраты за счет использования тригидрата ацетата натрия в виде побочного продукта производства полиэфиров и исключения использования этанола. Thus, the proposed method for producing a feed additive based on sodium diacetate can reduce costs by using sodium acetate trihydrate as a by-product of the production of polyesters and eliminating the use of ethanol.
