Abstract: Alkoxylated alcohols containing no insoluble matter which would prevent the spray application of such materials are obtained by reacting an alcohol and epoxide in the presence of a catalytic amount of a calcined hydrotalcite catalyst to form a crude alkoxylated product. The crude product is then passed through silica gel to remove insoluble by-products.

Abstract: The practicality of known depolymerization reactions in which there is a danger of building up adherent residues on heat transfer surfaces is greatly improved by performing the process under conditions that provide a driving force which assures that none of the feed material and none of any liquid or solid residue produced during the depolymerization of the feed material remains in contact with any heat transfer surface for a time sufficiently long to form any adherent solid residue on the surface. A preferred apparatus for achieving such a driving force includes a horizontal thin film evaporator, a controlled continuous input of liquid feed material, and continuous collection of desired reaction product and any residue that remains condensed throughout its passage through the reaction zone.

Abstract: This invention relates to an improved process for the preparation of 3-acyl-5-alkyldihydro-2(3H)-furanones according to the following reaction scheme: ##STR1## wherein R and R.sub.1 are hydrogen or alkyl and R.sub.2 is a hydrocarbon or -O-hydrocarbon radical of from 1 to 20 carbon atoms and X is a leaving group.

Abstract: A class of isoxazoles having a phenyl or substituted-phenyl group at the 3-position and a substituted-methyl group at the 5-position are useful for the control of fungal foliar phytopathogens.
