Description
Предметом изобретени вл етс способ получени клеющего препарата из сложных эфиров целлюлозы и серной кислоты.The subject of the invention is a process for the preparation of an adhesive preparation from cellulose esters and sulfuric acid.
Особенность способа заключаетс в том, что в качестве целлюлозного компонента примен етс отход, получаемый при очистке хлопкового семени (улюка).The peculiarity of the method lies in the fact that as a cellulosic component is used the waste obtained during the cleaning of cotton seed (uluk).
Клеюнщй препарат получают следующим образом.The adhesive preparation is prepared as follows.
Отвешенное количество отхода, полученного при очистке хлопкового се-мени, постепенно нри размешивании внос т в сосуд, в котором нахо .1ИТСЯ коицентрирбванна серна кислота в двойном количестве (но весу ) от отхода. Темнература при этом не до.тжна превышать 30°, что достигаетс охлаждением сосуда.The weighed amount of waste obtained during the cleaning of the cotton seed is gradually introduced into the vessel, while stirring, in which the sulfuric acid is concentrated in a double amount (but weight) of the waste. The temperature at the same time does not exceed 30 °, which is achieved by cooling the vessel.
После внесени всего отхода массу нродолжают размешивать периодически . Продолжительность реакции сульфировани зависит от концентрации серной кислоты, температуры и интепсивиости размешиван г и считаетс законченной после того, как получаетс однородна густа масса.After all the waste has been added, the mass is kept stirring periodically. The duration of the sulphurization reaction depends on the concentration of the sulfuric acid, the temperature and the intakeability of the mixture and is considered complete after a homogeneous thick mass is obtained.

После этого приступают к нейтрализации свобод юй серной кислоты известковым молоком. При этом температура также не должна превышать 30°. Количество извести, необходимое дл нейтрализации, вычисл етс по количеству cepHoii кислоты , вз той дл сульфировани . Рекомендуетс процесс 1ейтрализацииAfter that, they proceed to the neutralization of free sulfuric acid with lime milk. At the same time, the temperature should also not exceed 30 °. The amount of lime needed to neutralize is calculated from the amount of cepHii acid taken for sulfonation. A neutralization process is recommended.
