Abstract: A method of preparing enhanced reactive vegetable oils wherein the method comprises providing a hydroxy functional vegetable oil having a predetermined hydroxyl value and, under nitrogen, treating the hydroxyl functional vegetable oil with a catalyst using heat and pressure. Any water that is formed is removed. The mixture is heated under pressure and then an alkylene oxide is added while heating under pressure. In one embodiment, thereafter, there is added ethylene oxide and the material is heated and then the material is neutralized with acid. This process results in a primary hydroxyl functional vegetable oil polyol that is an enhanced reactive vegetable oil.

Abstract: A method for producing a chroman-carboxylic acid is provided, which method includes reacting a dialkylphenol compound, a formaldehyde and an alcohol in the presence of a secondary amine and an acid to give an alkoxymethylated phenol compound (Step 1); reacting the obtained alkoxymethylated phenol compound with an ester having a carbon-carbon double bond at a temperature of not less than 100° C. to give a dialkylchroman carboxylic acid ester (Step 2); hydrolyzing the obtained dialkylchroman carboxylic acid ester to give a dialkylchroman-carboxylic acid (Step 3); and reacting the obtained dialkylchroman-carboxylic acid with an aromatic hydrocarbon in the presence of a Lewis acid (Step 4).

Abstract: The invention relates to a method for producing formaldehyde from methanol by non-oxidative dehydrogenation, in a reactor, in the presence of a catalyst at a temperature between 300 and 1000° C. Said method is characterized in that the generation of the catalyst takes place spatially separate from the reactor and at a temperature greater than the dehydrogenation.

Abstract: Disclosed is a process to produce paraformaldehyde prills having a low dissolution time and low concentration of insoluble formation. The insolubles are believed to lead to stickiness, tackiness, and loss of flowability of the product, loss of handling, and lead to storage problems of the final prill product. To address this problem, a concentrated formaldehyde solution is prepared having a purity ranging from 37%-99% and may be mixed with an amine additive, an amine and alcohol additive, or amine, alcohol, and caustic additive. Alternatively, the final prill may be sprayed with an amine or amine mixture stabilizer.

Abstract: Use of perfluoropolyethers with non reactive terminals or compositions thereof for the prevention and/or the treatment of topical vital infections, in particular of Herpes Simplex I and II and of Herpes Zoster.

Abstract: Polyether polyol comprising as alkylene oxide units ethylene oxide and propylene oxide units, said polyol having a nominal average hydroxyl functionality of 2-6, an hydroxyl value of 16-45 mg KOH/g, a primary hydroxyl content of at least 50% calculated on the total amount of hydroxyl groups and an amount of ethylene oxide units, calculated on the weight of the alkylene oxide units in the polyol, of 21-49% by weight these polyols are useful for making flexible foam.

Abstract: Condensates (K) of(A) oligohydroxy-C.sub.3-8 -alkanes containing at least 3 hydroxy groups and (B) KOH,that contain at least 5% by weight of K.sup.+ and at least one alcoholic hydroxy groupare eminently suitable as oxyalkylation catalysts, in particular for the oxyalkylation of ester group-containing substrates, before all of natural, vegetable or animal fats or oils or their modification products.

Abstract: An in-situ biocide having improved characteristics comprises polyoxymethylene polymers having an inherent viscosity of at least 0.1 as measured in para-chlorophenol at 60.degree. C. Such polymers provide continuous release of formaldehyde biocide in hydrocarbon production, transportation, ans storage systems by long term decomposition of the polyoxymethylene. The polyoxymethylenes used are water-insoluble materials, wherein decomposition rate can be controlled through the use of pH, temperature, and certain decomposition catalysts.

Abstract: The invention relates to a process for the halogenation of organic compounds in the liquid phase using gaseous halogenating agents, the gaseous halogenating agents being metered into the reaction vessel at such an entry velocity that a gas jet is formed in the reaction mixture at the point of entry of the halogenating agent and the formation of individual gas bubbles at the point of entry is prevented.

Abstract: Tert.-butoxybutanals and tert.-butoxybutanols (I) and bis-tert.-butoxypentanals and bis-tert.-butoxypentanols (II) ##STR1## where R.sup.1 and R.sup.2 are H or C.sub.1 -C.sub.4 -alkyl, one X is --CHO or --CH.sub.2 OH and the others are H.These compounds, which are valuable as fragrances and for use in organic syntheses are obtained by hydro-formylating the ethers (III) and bis-ethers (IV), respectively, using Rh catalysts.

Abstract: Equimolar amounts of phenol and formaldehyde may be prepared from oxygen and toluene. The catalytic oxidation of toluene, when carried out in the presence of acetic anhydride, forms phenyl acetate and methylene diacetate. Pyrolysis of these two intermediates yields phenol and formaldehyde.Significant improvements in this process are achieved when the first stage of the reaction is carried out in the presence of MoO.sub.3.In a further embodiment of this invention it has been found that Group VIII dithiosemibenzil compounds, particularly nickel dithiosemibenzil, serves as a superior promoter for the toluene oxidation reaction.In still a further embodiment of this invention it has been found that persulfate promoters such as potassium persulfate, persulfuric acid, or Caro's dry acid are particularly effective promoters for the toluene oxidation reaction.In a like manner, hydroquinone or resorcinol may be obtained from cresyl acetates.
