Abstract: A process for selective cracking of 1,4-disubstituted benzene compounds having at least one polar substituent. Mixtures containing isomers of such a compound are brought into contact with a specified type of shape selective crystalline zeolite catalyst under conditions of temperature and pressure conducive to reaction of said benzene compound, thereby selectively reacting the 1,4-disubstituted isomer in preference to the 1,2- and 1,3-disubstituted isomers of said polar benzene compound. The shape selective zeolite catalysts employed herein are crystalline zeolites characterized by a silica to alumina ratio of at least about 12 and a constraint index within the approximate range of 1 to 12.

Abstract: Compounds of formula I wherein R.sup.1 and R.sup.2 are haloalkyl or halo, X is O, S, S(O), SO.sub.2 or NR.sub.4 where R.sub.4 is H or alkyl, R.sup.3 is alkyl and n is 1 to 4, and compositions comprising them, useful as insecticides.

Abstract: A process for artificially modifying atmospheric precipitation wherein a liquid composition containing dimethyl sulfoxide as the principal ingredient is dispersed into the atmosphere from a container in microdroplet form having an average diameter ranging from 1 to 10 microns.

Abstract: Hydroxyalkylphenyl ether or thioether compounds are prepared by reaction of cyclic organic carbonate compounds with phenols or thiophenols in the presence of an alkali metal halide catalyst.

Abstract: This invention provides a convenient and commercially adaptable process for the preparation of vinylcyclopropane derivatives in high yield. For the process an alkylating agent and activated methylene compound are reacted in the presence of an alkylene oxide derivative and alkali metal compound. Water can also be present and/or the reaction may be carried out in an inert organic diluent.

Abstract: Fluoroalkoxysulfur fluorides of the formula ##STR1## wherein R is H, CH.sub.3, CF.sub.3, or C.sub.2 F.sub.5, and n is 1 or 2; their preparation by reaction of lithium fluoroalkoxides with sulfur tetrafluoride; their use as fluorinating agents to replace OH groups in organic molecules with F; and halocarbon solutions of lithium fluoroalkoxides.

Abstract: Active hydrogen-containing fluorochemical is used as a foam stabilizer for polyurethane foams. For example, rigid or flexible polyurethane foams with high or low density and uniform cellular structure are prepared using fluoroaliphatic radical-substituted poly(oxyalkylene) polyols as foam stabilizers.
