Description
Известен способ изготовлени диспергатора нейтрализацией продукта конденсации бета-сульфокислоты нафталина с формалином раствором едкого натра.A known method of manufacturing a dispersant is neutralizing the condensation product of naphthalene beta-sulfonic acid with formalin sodium hydroxide solution.
Предлагаемый способ изготовлени диспергатора позвол ет исключить применение едкого натра и улучшить физико-химические свойства диспергатора. Это достигаетс тем, что дл нейтрализации продукта конденсации примен ют аммиак вместо едкого натра. Получаемый таким образом диспергатор имеет более низкую точку застывани (от-6 до-8°), чем известный диспергатор ( + 10°); водные растворы диспергатора более стабильны и получаютс с более высокой концентрацией (). Диспергирующие свойства его на 15-20% выше, чем у диспергатора, изготовленного с применением едкого натра. Технологический процесс изготовлени диспергатора с применением аммиака значительно ускор етс , в частности, на операции фильтрации.The proposed method of manufacturing a dispersant eliminates the use of caustic soda and improves the physicochemical properties of the dispersant. This is achieved by using ammonia instead of caustic soda to neutralize the condensation product. The dispersant thus obtained has a lower solidification point (from −6 to −8 °) than the known dispersant (+ 10 °); aqueous solutions of the dispersant are more stable and are obtained with a higher concentration (). Its dispersing properties are 15–20% higher than those of a dispersant made with the use of caustic soda. The manufacturing process for the manufacture of a dispersant using ammonia is significantly accelerated, in particular, in filtering operations.
