Description
бового остатка аэеотропного разделени перегнанной жижки лесохимического производства.residual balance of aerootropic separation of distilled slime of wood chemical production.
К смеси при перемешивании добавл ю 7,2 л 40%-ного водного раствора НаОН а затем свежеприготовленное известковое молоко в количестве 5 л, содержащее 0,45 СаО и перемешивают 1 ч. В течение всего процесса температура в реакторе поддерживалась 70-80 с за счет теплоты нейтрализации.While stirring, to the mixture was added 7.2 l of a 40% aqueous solution of NaOH and then freshly prepared milk of lime in an amount of 5 l containing 0.45 CaO and stirred for 1 hour. During the whole process, the temperature in the reactor was maintained 70-80 s for account heat of neutralization.
Избыток экзотермического тепла отвод т вод ной рубашкой реактора .Excess exothermic heat is removed by the water jacket of the reactor.
Выход продукта составл ет 100% от добавленных дл реакции сухих реагентов .The yield of the product is 100% of the dry reactants added for the reaction.
Полученный продукт имеет следующие характеристики: водорастворимость, полна , рН 12, содержание сухих веществ 56%.The resulting product has the following characteristics: water solubility, complete, pH 12, solids content 56%.
Пример 2, К 12,5 кг древесной пирогенной СМОЛЬ (содержание сухой смолы 10 кг) при перемешивании ввод т 0,5 кг кубового остатка азеотропного разделени перегнанной жижки, к смеси добавл ют при перемешивании 8 л 40% -ного водного раствора NaOH, а затем 3,5 л известкового молока, содержащего 0,3 кг СаО.Example 2 To stirring in 12.5 kg of wood pyrogenic SMOLE (dry resin content 10 kg), add 0.5 kg of the azeotropic separation of distilled slurry to the mixture, add 8 l of 40% aqueous NaOH solution to the mixture while stirring, then 3.5 liters of milk of lime containing 0.3 kg of CaO.
Выход продукта I00%. Содержание сухих веществ 65%, рН 11,9.The product yield is I00%. The dry matter content is 65%, pH 11.9.
Пример 3. К 12,5 кг древесной пирогенной смолы ввод т при перемешивании 2,5 кг кубового остатка азеотропного разделени перегнанной жижки. Дл нейтрализации добавл ют при перемешивании 9,2 л 40%-ного водного раствора NaOH и 5 л известкового молока, содержащего 0,5 кг СаО.Example 3. To 12.5 kg of wood pyrogenic resin, 2.5 kg of the bottom residue of azeotropic separation of distilled slurry was added with stirring. For neutralization, 9.2 L of 40% aqueous NaOH solution and 5 L of milk of lime containing 0.5 kg of CaO are added with stirring.
Выход продукта Product yield
I00%, содержание сухих веществ 67% о рН 11,8. Сравнительные физико-механические показатели пенообразующих добавок, получен ных предлагаемым способом иизвестным , приведены в таблице.I00%, dry matter content 67% about pH 11.8. Comparative physicomechanical indicators of foaming additives obtained by the proposed method and known are given in the table.
