DE721792C - Process for the production of resinous compounds containing sulfur and chlorine - Google Patents

Description

Process for the production of sulfur- and chlorine-containing resinous Masses The conversion of conjugated double bonds containing oils or higher molecular weight Fatty acids, such as oil, linseed oil and their breakdown products, in so-called factice with the help of halogenated sulfur, e.g. B. chlorosulfur is known. The requirement for this Reaction forms the presence of the conjugated double bonds.

It was therefore surprising that in the treatment of liquid to semi-liquid so-called sulphate pitch, d. H. Tall oil still residue, the conjugated one Has no double bonds at all, with io to zoojö halogen sulfur at 6o to 70 ° resin-like substances are formed, depending on the amount of halosulfur used Can turn out balsam-like to spring-hard and as a substitute for a number of resins as well can also serve as a relatively light-colored substitute for asphalt. As halogen sulfur all technically accessible products can be used, primarily of course sulfur chloride (S2C12) and sulfur chloride (SC12).

One can use the finished products in a similar way as they contain carboxyl groups like other compounds bearing carboxyl groups in oils, they also esterify or ester further processing in a different way, for example by amide formation or through the formation of lime, magnesium or metal salts.

. It has already been proposed to use plastic masses and the like Treatment of tall oil distillation residues with sulfur to generate heat. However, as has been established by experiments, completely different products are used here than after the. present invention obtained, namely brittle, resinous, dark and very foul smelling crowds, perhaps for some Molding compounds are suitable, but for paint purposes their smell and their poor binding power because of are unsuitable. In addition, these masses differ from those after present invention in that they are free according to their method of manufacture are of organically bound chlorine.

Neither has the known treatment with the present invention of crude tall oil to do something with chlorosulfur that is only sticky, balsamic Masses are preserved. Even when applying these compounds to a base nor drying agents of the usual type are added, it is not possible to drying paints to come, while the resinous paints according to example i of the present invention result in paints that dry well. Examples i. In 50o parts by weight Sulphate pitch is allowed to drop in at 60 ° to 70 ° within two and a half hours, 100 g of chlorosulphur and stir until the evolution of hydrochloric acid has ended. It becomes 56o parts by weight obtained from a viscous resin, hard as a spring in the cold, with a chlorine content of 2.80`o was determined. The resin is expediently immediately in a solvent solved. A 35% benzene solution is suitable as an economical paint varnish for wood and the like and forms completely waterproof films.

z. In 50o parts by weight of sulfate pitch one leaves below those in the example i mentioned conditions run in 5o parts by weight of chlorosulphur and receives 53o Parts by weight of a soft resin of extremely strong bond strength in which a chlorine content of 1.6o'o was found. This resin can, in suitable solvents solved, especially for the preparation of linoleum putty.
