Abstract

297,430. Nes, G. E. van. Sept. 21, 1927, [Convention date]. Purifying saccharine liquids. - In purifying aqueous solutions a solution of a lyophyl colloid or a substance which will form a lyophyl colloid is added to the liquid and a, coarsely dispersed precipitate is then produced by the addition of an acid and a base, the operation being conducted at a suitable temperature and hydrogen-ion concentration, so that the colloid is precipitated and can be separated, with colouring matters and other impurities, by filtration or decantation. Albumen, starch, amylum and silica are suitable colloids. The coarse precipitate may be formed by adding successively a base and an acid. In one example albumen is added to raw cane juice, which is then carbonated by means of lime and carbonic acid. In a second example, water-glass is added to diluted cane-sugar molasses, which is then carbonated with lime and carbonic acid. Magnesia, baryta or aluminium, oxide may be used instead of lime and sulphurous or phosphoric acid instead of carbonic acid. Specifications 13702/09, [Class 46, Filtering &c.], 173,735; 177,761 and 225,635, [both in Class 46, Filtering &c.], are referred to.
