Abstract: A process for producing chloro-s-triazine trione with improved crystal properties comprising reacting cyanuric acid, alkali metal hydroxide, and chlorine in water, and crystallizing the resulting chloro-s-triazine trione in the presence of an alpha olefin sulfonate with from 4 to 20 carbon atoms.

Abstract: Solvents useful to dissolve dyes employed in pressure-sensitive copying systems comprise compositions of monobenzylated, dibenzylated and, optionally, tribenzylated xylenes having defined isomeric configurations. Benzylated meta-xylene; benzylated para-xylene; and benzylated meta-para-xylene are low-odor solvents.

Abstract: An improved method of transmitting power in hydraulically-operated mechanisms which comprises using as the operative fluid substantially completely hydrogenated dimers of alpha-methylstyrene, e.g. 2,4-dicyclohexyl-2-methylpentane.

Abstract: Dimers of .alpha.-alkyl styrene consisting of linear dimers with up to about 20% of cyclic dimers are substantially completely hydrogenated to improve the coefficient of traction of the dimers and to yield a composition comprising a major proportion of compounds having the general structure ##EQU1## wherein each R is an alkyl of 1 to 4 carbon atoms. These compositions are liquids which have good viscosity properties over a wide temperature range, have excellent oxidative stability, and are particularly useful as tractive fluids in applications requiring low temperature operability.
