Abstract
115,421. Bennert, C. April 30, 1917, [Convention date]. Albumens &c.-Products of the type of protalbinic and hysalbinic acid are obtained by hydrobyris of waste chrome leather shavings or cuttings by dilute alkalis. According to examples : -Chrome leather shavings are treated with hot dilute caustic soda lye, the liquor is cooled, filtered, neutralized with formic or acetic acid, and concentrated in vacuo to a syrupy consistency; chrome leather cuttings are boiled in water, treated with very dilute caustic alkali lye, then stirred with water and sand or pumice to remove varnish and colouring matter, again boiled with water, finally decolourized by bleaching agents, and then hydrolyzed as described above. The products are intended for use in the textile industries. Specification 6103/89, [Class 76, Leather], is referred to. The Specification, as open to inspection under Sect. 91 (3) (a), refers also to the treatment of waste leather in general, including vegetable tanned leather, by the process described above. This subject-matter does not appear in the Specification as accepted.
