Abstract: A process for making an alkali metal alkoxide (e.g. sodium alkoxide) of a halogen-substituted alcohol (e.g. fluorine-substituted alcohols) by dispersing an alkali metal (e.g. sodium) in a cycloalkane (e.g. cyclohexane) containing a phenol (e.g. o-allylphenol) and adding the resultant dispersion to an ether (e.g. THF) solution of a halogen-substituted alcohol. The resultant alkali metal haloalkoxide solution contains phenoxides and can be reacted with a phosphonitrilic chloride polymer to introduce haloalkoxide and phenoxide substituents.

Abstract: Compounds of the general formula I: ##STR1## wherein R.sub.1 and R.sub.2 are equal or different alkyl-, alkoxyalkyl-, or aryl groups, or together form a ring; R.sub.3 is an allyl or benzyl radical; and R.sub.4 and R.sub.5 represent hydrogen, alkyl, alkoxyalkyl, alkenyl or further compounds of the formula II: ##STR2## wherein R.sub.1, R.sub.2, R.sub.4 and R.sub.5 have the meaning indicated above and R.sub.6 stands for hydrogen or methyl or to compounds which are modified by the addition of hydrogen to at least one olefinic or carbonylic double bond of compounds of the general formula I or II. The invention also relates to a process for preparing the new compounds. The compounds of the general formula II are obtained by thermal treatment of a selection of compounds of formula I, for which R.sub.3 stands for the allyl or methallyl radical. The compounds according to the invention are used as fragrant and flavoring substances.
Abstract: Disclosed is a process for preparing 4-haloalkyl alcohols by reacting tetrahydrofuran derivatives and hydrogen halides in the presence of a resinous quaternary ammonium halide catalyst, preferably styrene-divinyl benzene copolymer resins having pendant N(R).sub.3 X, where X is halogen, or N(R).sub.2 groups of tetrahydrofuran. The haloalcohols are useful intermediates for the preparation of dyes, halogenated polymers, pharmaceuticals, polymerization catalysts and plasticizers.
Abstract: This invention relates to the method for making ethylene oxide, characterized by the fact that ethylene oxide in the gaseous state is made to react with anhydrous gaseous hydrochloric acid, with the reaction medium likewise being maintained in the gaseous state during the reaction.

Abstract: The present invention provides a novel process for the production of 1-phenyl-3-(3-trifluoromethylphenyl)-2-propanone. The process comprises the steps of:(a) condensing 3-trifluoromethylbenzaldehyde with acetophenone under basic conditions to form a substituted chalcone,(b) epoxidation of the substituted chalcone to produce the corresponding epoxide,(c) converting the epoxide to a chlorohydrin,(d) catalytic hydrogenolysis of the chlorohydrin to produce a diol and subsequently converting the diol into the corresponding alcohol, and(e) oxidizing the alcohol to produce 1-phenyl-3-(3-trifluoromethylphenyl)-2-propanone.
Abstract: Novel substituted propargyl alcohols of the formula: ##STR1## novel allylic alcohols of the formula: ##STR2## .delta.,.epsilon.-unsaturated ketones of the formula: ##STR3## are provided. In the above formulas, R represents a group of the formula: ##STR4## wherein X.sub.1 and X.sub.2 are both hydrogen atoms or wherein one of X.sub.1 and X.sub.2 is a hydrogen atom, the other jointly with Z represents a bond; Z jointly with X.sub.1 or X.sub.2 represents a bond or separately represent a hydrogen atom, a hydroxyl group or a lower alkoxy group; R.sub.1 and R.sub.2 are the same or different and represents hydrogen atoms or lower alkyl groups; n is 1 or 2; and when n is 2, X.sub.1, X.sub.2, X, R.sub.1 and R.sub.2 may be the same or different. These novel compounds are easily produced and are useful as perfumes and as interrelated intermediates for the production of terpenoid compounds.
