A pigmented vinyl chloride composition is provided which has a whitening and opacifying package comprising titanium dioxide and a titanium dioxide replacement/extender. The replacement/extender replaces up to 30 percent by weight of the titanium dioxide and yet maintains one or more selected optical property as if the whitening and opacifying package were pure titanium dioxide. These optical properties include the Yellowness Index, the DE* value and the percentage light transmittance. The extender is one or more of an alkaline earth metal titanate, lanthanide titanate, or aluminum titanate.

Disclosed are polyvinyl chloride and polyvinyl chloride type compositions using a titanium dioxide based whitening/opacifying package containing up to about 30 percent by weight of an aluminosilicate composition. In the whitening/opacifying package the aluminosilicate composition acts as a replacement for the same amount by weight of titanium dioxide. The whitening/opacifying package achieves a measure of overall appearance (DE* value), a Yellowness Index, and a percentage of light transmitted (opacity) which are substantially comparable or superior to those achieved by the same weight of pure titanium dioxide.

Corrosion of ferrous metal and aluminum surfaces, in particular, is inhibited by a layer of an organic-metallic complex of a polyamine with a (i) metal oxide, or (ii) metallate ion, or (iii) water-soluble metallate salt, in aqueous systems having a pH greater than about 7. The polyamine contains at least four (4) amine groups, two of which are secondary amine groups. The effect of the N atoms stretched over the length of the polyamine produces a 'caging effect'0 which immobilizes the oxide, or metallate ions, thus forming the protective layer. The organic-metallic complex deposited on the metal's surface forms the 'amine-metallic' layer which may be either an 'amine-metal oxide complex' which is a coordination complex, or, an 'amine-metallate complex'. The amine-metallate complex may be either an ionic complex of 'amine.metallate ions', or, a mixture of the polyamine and metallate salt which mixture is not a complex, but in solution, behaves like one, and is therefore referred to as an admixture complex of an 'amine+metallate salt'. The organic-metallic complex may be present in a concentration from about 10 ppm to about 5% by wt in neutral or basic aqueous solution. In the lower range of this conc. up to about 2000 ppm, the complex is useful in aqueous process streams; in the higher range, from 2000 ppm to 5%, for a rinse for phosphated metal parts, in lieu of a conventional chromate rinse.

Process for inhibiting corrosion of metal and corrosion-inhibiting layer

An alkane is reacted with oxygen and available chlorine in the presence of a solid solution catalyst containing iron cations to yield unsaturated hydrocarbons and chlorinated saturated and unsaturated hydrocarbons. In a preferred embodiment of the process, ethane is reacted with oxygen and available chlorine in the presence of a solid solution catalyst containing iron cations to yield vinyl chloride, ethylene, and other valuable by-products. The conversion of ethane to products approaches 100 percent, vinyl chloride is prepared in up to 40 mole percent yield, and the combined yield of vinyl chloride, ethylene dichloride, ethyl chloride, and ethylene is up to 90 mole percent.

Amine molybdates are formed by reacting an amine with a molybdenum compound in a reaction mixture comprised of at least two immiscible liquid materials, one of which is an aqueous phase and another of which is a volatile organic solvent in which the amine molybdate to be formed is readily soluble. An inorganic or organic acid desirably is added to the reaction mixture.
