Description
Уже давно установлено на практике , что из жиров лучшими неногас щими Свойствами обладает касторовое , а затем кокосовое масло и что жирные кислоты обладают лучшими пеногас ШИми свойствами, чем жиры. В свете современных теорий данные практики можно объ снить значительно большей гидрофильностъю жирных кислот, чем жиров, а из жиров большей гидрофильностью касторового масла (присутствие оксикислот) и кокосового масла (высокий коэфициент омылеНИЯ ).It has long been established in practice that among fats, castor and then coconut oil have the best non-extinguishing properties, and that fatty acids have better defoaming properties than fats. In the light of modern theories, these practices can be explained by the significantly greater hydrophilicity of fatty acids than fats, and from fats, the greater hydrophilicity of castor oil (the presence of hydroxy acids) and coconut oil (high saponification).
в насто щее врем в качестве пеногасител в дрожжевом- и других производствах примен етс , главным образом, олеилова ккслота , котора вл етс относительно дорогим продуктом.At present, oleyl acid, which is a relatively expensive product, is mainly used as antifoam agent in yeast and other industries.
Предлагаемый .способ гашени пены заключаетс в применении -в качестве пеногас щего реагента гиддрофильных липинов, получаюш,ихс . путем окислени масел воздухом.The proposed method of quenching the foam is to use hydrodrophilic lipins as a defoaming agent, which gives them. by oxidizing oils with air.
Пример. Пеногаситель дл дрожжевой промышленности получают следук щи)м o6pai3 JM.Example. Antifoam for the yeast industry is obtained by following the following steps.
В сосуд 1 (см. чертеж) наливают растительное масло (льн ное, хлопковое , подсолнешое, конопл ное) неIn vessel 1 (see drawing), pour vegetable oil (flaxseed, cottonseed, sunflower, hemp) not
более, чем на 40% его емкост ;. Затем сосуд с маслом помеш,ают в масл ную или песчаную баню 2 (в том случае, если нет паровой рубашки ) ДЛЯ1 обогрева, которое производитс одновременно с пропусканием .воэдуха через бар ботер 3, причем температура масла доводитс до 200°.more than 40% of its capacity; Then the vessel with oil is placed in the oil or sand bath 2 (if there is no steam jacket) FOR1 heating, which is carried out simultaneously with passing the air through the bar 3, and the temperature of the oil is adjusted to 200 °.
Процесс окислени заканчиваетс после п тичасового пропускани воздуха (лучше подогретого) через масло, температуру которого все врем поддерживают равной 200°.The oxidation process ends after five hours of air (preferably warmed up) through the oil, the temperature of which is maintained at 200 ° all the time.
Минимальное количество воздуха, необходимое дл окислени 1 кг маола, - 40-60 литров в час.The minimum amount of air needed to oxidize 1 kg of maola is 40-60 liters per hour.
Готовый пеногаситель имеет консистенцию нагретого стол рного кле и употребл етс- дл пеногашени как в гор чем, так и в холодном состо нии.The prepared defoamer has the consistency of heated table glue and is used for defoaming both in the hot and cold state.
Выход пеногасител практически равен 100%.The output of the antifoam is almost 100%.
Предмет изобретени Subject invention
Применение гидрофильных липинов , получающихс путем окислени растительных масел воздухом, в качестве пеногас щего реагента.The use of hydrophilic lipins, obtained by oxidizing vegetable oils with air, as an antifoaming agent.
