Abstract: A method for the production of finely particulate solid chemical products from a molten stock comprises the steps of: (a) feeding the product, as molten stock, to an elongated treatment space, sealed from the ambient; (b) causing the product to flow as a flowable mass within space, while leaving a free portion of said space above the surface of said mass; (c) maintaining in said space an atmosphere that is non-reactive with said product; (d) subjecting said product to a stirring and mixing action by rotary means; (e) concurrently cooling said product as it proceeds along said space, whereby to solidify it; (f) concurrently detaching any product that adheres to surfaces within said space; and (g) discharging the solidified product, in the form of solid particles, from said elongated treatment space.

Abstract: Mixtures of 2-methyl-isothiazolin-3-one (5H-MIT) and 5-chloro-2-methylisothiazolin-3-one (5Cl-MIT), are prepared by the chlorination of N-methyl-3-mercaptopropionamide (MMPA) with chlorine in a halogenated solvent in continuous operation.

Abstract: Octyl methoxy cinnamate of the formula ##STR1## is prepared by reacting p-bromoanisole with octyl-acrylate in an inert solvent, in the presence of a base and of a coupling catalyst.

Abstract: The present invention relates to a method for beneficiation of phosphate rock by a thermal treatment, wherein an appreciable increase in P.sub.2 O.sub.5 and decrease in cadmium contents in the calcined product are achieved. According to the invention, the phosphate rock is contacted with hot gases possessing a temperature in the range of between 700.degree. C. to 1600.degree. C. for a period of below 60 seconds and subsequently the fines are removed by a conventional classification method thus obtaining an up-graded phosphate product with a relatively low cadmium content. The up-graded phosphate product is also characterized by a relatively low sulfide content as well as low organic matter, which are very advantageous in the phosphoric acid manufacture therefrom. One of the advantages of the method is the almost complete recovery of the P.sub.2 O.sub.5 present in the phosphate rock since no slaking for calcium oxide removal is utilized.
