Abstract: The invention relates to a process for preparing alkyl chlorides by reacting alcohols with gaseous hydrogen chloride in the presence of a catalyst, wherein the catalyst comprises at least one compound of the structure: wherein R1 is a linear alkyl group having from 1 to 20 carbon atoms, R2, R3, and R4 is selected from a hydrogen, an alkyl, an alkenyl, an aralkyl or an alkylaryl group from 1 to 20 carbon atoms, wherein the substituents of R2, R3, and R4 are all identical, are all different or two of the substituents of R2, R3, and R4 type are identical.

Abstract: A process for stabilizing cyclobutanone derivatives, comprising adding at least one of an alkali metal carbonate, alkali metal oxide, alkaline earth metal carbonate, and alkaline earth metal oxide as a stabilizer to at least one cyclobutanone derivative of the structure where R1, R2, R3, R4, R5 and R6 are each independently hydrogen or an alkyl, aralkyl, cycloalkyl, aryl, alkylaryl, hydroxyl, alkoxy, halogen, cyano or carboxyl group; and the correspondingly stabilized cyclobutanone derivatives.

Abstract: The present invention is directed to a process for the synthesis of monoalkylated C—H acidic methylene group-containing compounds, such as malonic esters, and malonic ester nitriles.

Abstract: A salt-free process for preparing cyclobutanone, including isomerizing cyclopropylmethanol, preferably in aqueous solution, in the presence of an acidic heterogeneous catalyst to form cyclobutanol and, preferably after extraction and removal of the extractant, dehydrogenating the cyclobutanol over a heterogeneous catalyst.
