Abstract

257,258. I. G. Farbenindustrie Akt.- Ges. Aug. 21, 1925, [Convention date]. Waxes, extracting.-The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of halogen alkyl esters of mono- or polybasic carboxylic acids including carbonic acid, as solvents for waxes, and it mentions as suitable esters the dichlorethyl ester of carbonic acid, propionic acid chlorethyl ester, phthalic acid dichlorethyl ester, and the corresponding chlor- and brom-propyl esters. This subjectmatter does not appear in the Specification as accepted.
