Abstract: Water-soluble, polymerizable, acid addition salts of methacrylic acid and 2-mono-(lower)alkylanimoethyl methacrylate whose lower alkyl group is straight or branched chain or cyclic and has up to about 6 carbon atoms, said addition salt includes its methacrylic acid and methacrylate components in the ratio of from about one mole to about 1.5 moles of one of them per mole of the other.
Abstract: A pyrido [3,4-d] pyridazine derivative is provided herein of the formula: ##SPC1##Wherein R.sub.1 is hydrogen or an alkyl group of 1 to 4 carbon atoms; R.sub.2 is an alkyl group of 1 to 4 carbon atoms, an aralkyl group of 7 to 8 carbon atoms, or a substituted or unsubstituted phenyl, naphthyl, furyl or pyridyl, the substituent being a lower alkoxy group of 1 to 3 carbon atoms, a lower alkyl group of 1 to 3 carbon atoms, halogen or nitro; R.sub.3 is hydrogen or a lower alkoxy group of 1 to 4 carbon atoms; and R.sub.4 is a substituted or unsubstituted morpholino, piperidino or pyrrolidino, the substituent being methyl or ethyl and a pharmaceutically acceptable salt thereof. The compounds of the present invention have effective and strong diuretic action and exhibit extremely low toxicity characteristics.
Abstract: Substituted alpha-chloro-methane-sulfenyl chlorides, intermediary chlorinated benzyl sulfides and chlorinated mercaptans useful as herbicides and chemical intermediates for herbicides are prepared by the chlorination of substituted methyl benzyl sulfides and substituted methyl mercaptans.
Abstract: An improved process for oxacylating olefins in the gaseous phase which comprises using a supported catalyst comprising palladium and a carrier having a total pore volume of from 0.4 to 1.2 ml/g, less than 10% of the total pore volume being attributable to micropores having a diameter of less than 30 A. Catalysts of this type are much more efficient than conventional catalysts.
