Abstract: An esterification process for producing glycol ether esters which comprises reacting a lower hydrocarbyl carboxylic acid with a glycol ether alcohol in the presence of a long chain alkyl substituted aryl sulfonic acid esterification catalyst, the alkyl radical having from 8 to 20 carbon atoms.

Abstract: An improved esterification process for producing volatile product esters by reacting a lower linear hydrocarbyl carboxylic acid with an alcohol containing from 2 to 10 carbon atoms, in a substantially non-aqueous medium, the improvement comprising minimizing the amount of acidic sulfate contained in the product ester by employing as the esterification catalyst a long chain alkylbenzene sulfonic acid catalyst, the alkyl radical containing from 8 to 20 carbon atoms, or mixtures of such catalysts.

Abstract: A hydrocarbonylation process for producing an aldehyde or a mixture of a ketone and an aldehyde which comprises:(I) forming a reaction mixture comprising:(a) a catalytic amount of a complex catalyst consisting essentially of rhodium in complex combination with:(i) a triorganophosphine, and(ii) a carboxylic acid having a phenyl group substituted at the para position with a non-reactive electron-withdrawing group, said phenyl group being free of further substitution and said electron withdrawing group being substantially non-reactive in said process;(b) an alpha-olefin having 2 to 5 carbon atoms,(c) carbon monixide, and(d) hydrogenwith the proviso that the reaction mixture has mole ratio of said carbxoylic acid to rhodium of at least about 2; and(II) maintaining the reaction mixture at a temperature and pressure at which said (b), (c) and (d) react to form an aldehyde or a mixture of an aldehyde and a ketone.

Abstract: The aldol condensation of acetone to isophorone and mesityl oxides in high conversions and efficiencies is achieved by a catalyst comprising a calcined calcium salt deposited on an alumina support.

Abstract: A process is disclosed for the aldol condensation of enolizable aldehydes to alpha, beta-unsaturated aldehydes, at high selectivities, employing a metal carboxylate catalyst.

Abstract: Crude isophorone is refined by contacting it with aqueous caustic followed by washing and fractional distillation.

Abstract: This invention relates to novel curative compositions for use in the production of cellular polyurethane elastomers having outstanding energy-absorbing properties. The curative compositions are composed of mixtures of organic diols and the reaction product of phenols which have at least one unsubstituted reactive position on the aromatic nucleus, aldehydes, and aromatic amines.

Abstract: Novel haloalkyl polyphosphates are prepared by reacting at elevated temperatures a halosubstituted alkyl phosphate such as, for example, tris (2-chloroethyl) phosphate, and an unsubstituted trialkyl phosphate such as, for example, triethyl phosphate. The character of the mixture of the thermal condensates formed can be influenced by the ratio of reactants employed and the extent to which the reaction is allowed to proceed. The resulting reaction products possess superior flame retardant efficiency and impart durable flame resistance when incorporated into flexible urethane foams.

Abstract: Novel polymethylol polyphosphonates are prepared by reacting a trisubstituted polyphosphite having at least one alkyl group and formaldehyde. The phosphite reactant may contain the requisite hydroxyl functionality [e.g. - heptakis (dipropylene glycol) triphosphite] or the hydroxyl functionality may be introduced by carrying out the reaction in the presence of a polyol, e.g. - glycerol, as a protic solvent. The resulting reaction product is a water-soluble liquid of relatively low viscosity and may be employed without any refining. The thus-formed polyphosphonates can be readily incorporated into either rigid urethane foam formulations to impart flame retardancy or phenolic resins to improve flexibility.
