Title: Improvements in or relating to the manufacture of hard wax-or resin-like condensation products
IPC: C08G79/08
Filed: 1936-01-16
Abstract: Insoluble wax- or resin-like condensation products are made by heating fatty or wax alcohols containing at least 6 carbon atoms, or fatty oxy-acid esters containing at least 6 carbon atoms in the acid residue with orthoboric acid, orthoboric-acetic acids, orthoarsenious or orthophosphorous acids, or their anhydrides, in a stream of inert gas.  Carnauba wax, beeswax, or montan wax alcohols, octadecanol, docosanol, hardened castor oil, octadecanediol, and pentatriacontanol are suitable initial materials.  The condensation may be effected above 100 DEG C. in the presence of condensing agents, solvents, or liquid or solid diluents, e.g. decahydronaphthalene, heavy benzine, hardened colza oil, spermaceti, paraffin, and ozokerite.  Time may be 2--40 hours or longer, generally 2--10 hours.  The products can be mixed with turpentine or mineral oils and may be used for shoe creams, floor waxes, polishes, adhesive greases and waxes, draw fats, for addition to candles or grafting wax, for impregnating textiles, for making gramophone records and other plastic or pressed masses, or glazed-paper.  In examples: (1) alcohols obtained by reduction of carnauba wax, and boric acid are heated at 160 DEG C. for 2 hrs. while passing CO2 and stirring.  The product is stirred for a further hour and then solidified.  It may be mixed with hardened colza oil, or with ozokerite, paraffin, and turpentine oil to produce a polish for leather and furniture; (2) octadecanediol is condensed as in (1) giving a white product suitable for addition to paraffin candles. The Specification as open to inspection under Sect. 91 is not limited to condensation in a stream of inert gas and refers to treatment in vacuo.  In an additional example, hardened castor oil is refluxed for 2 hrs. with boric acid and acetic anhydride to give a casting and impregnating wax.  In the absence of acetic anhydride, and after 40 hrs. at 180 DEG C., a ropy product is obtained setting to a whitish porcelain-like mass suitable for making artificial products and pressed masses.  This subject-matter does not appear in the Specification as accepted.ALSO:Insoluble wax- or resin - like condensation products are made by heating fatty or wax alcohols containing at least 6 carbon atoms, or fatty oxy-acid esters containing at least 6 carbon atoms in the acid residue with orthoboric acid, orthoboric-acetic acids, orthoarsenious or orthophosphorus acids, or their anhydrides, in a stream of inert gas.
