摘要： The present invention relates to metathesis syntheses for insect sex-attractant pheromones or their components, such as E-5-decenyl acetate, the major component of the Peach Twig Borer pheromone; (5R,6S)-6-acetoxy-5-hexadecanolide, the mosquito oviposition attractant pheromone; E9,Z11-hexadecadienal, the pecan nut casebearer moth pheromone; 9-tetradecenyl formate, an analog of the Diamondback Moth (DBM) pheromone; 11-tetradecenyl acetate, the Omnivorous Leafroller (OLR) pheromone; E-4-tridecenyl acetate, the major component of the Tomato Pinworm (TPW) pheromone; E,E-8,10-dodecadienol, the Codling Moth (CM) pheromone. The syntheses preferably employ a Class I-IV metathesis catalyst, entail few reaction steps, use generally commercially available starting materials, and have relatively short process times. These syntheses produce good yields without the need for expensive or sophisticated equipment. The invention also provides an inexpensive route for producing omega-haloalkenols by cross-metathesizing alpha-omega-diacetoxy alkenes and alpha-omega-dihalides to yield omega-haloalkenols, which are easily converted into omega-haloalkanols under traditional hydrogenation methods.

摘要： A process for the catalytic conversion of carboxylic acids with acetylene to vinylesters. At least one, preferably saturated, secondary carboxylic ester and/or at least one, preferably tertiary carboxylic acid is (are) passed in the gas phase together with acetylene at an elevated temperature, preferably in the range of from 150 to 400° C., over a catalyst comprising zinc and a solid inert oxidic carrier, preferably alumina. The carboxylic acids have advantageously the following formula: in which R1 is H or an alkyl group and R2 and R3 are alkyl groups, the total number of C-atoms of R1+R2+R3 being in the range of from 3 to 18. These vinylesters have a good stability and are particularly useful components in emulsion paints and as modifiers in alkyd and epoxy resin.

摘要： Process for the production of lower aliphatic esters by bringing together in an addition reaction a lower olefin and a saturated, lower aliphatic, mono-carboxylic acid in the vapor phase into contact with a heterpolyacid catalyst. The reactant olefin and acids and any recycled feeds are rendered substantially free of aldehydes impurities prior to being brought into contact with the heterpolyacid catalyst. Acetaldehyde is a catalyst poison and removal of these from the feeds prolongs life and activity of the heteropolyacid catalyst.
