Abstract: Described is a process for the preparation of a particulate tetrahydro-3,5-dimethyl-1,3,5-thiadiazine-2-thione product by combining a first aqueous solution comprising methylammonium N-methyldithiocarbamate with a second aqueous solution comprising formaldehyde, followed by separation and drying of the resulting solid, which comprises combining the first and the second aqueous solutions in such a way that the ratio between the concentrations of dithiocarbamate functions and of formaldehyde is essentially constant in the reaction mixture over time during the duration of the reaction.

Abstract: The present invention relates to a process for isomerizing reactant allyl alcohols to product allyl alcohols in the presence of a catalyst, wherein the reactant allyl alcohol is rearranged to product allyl alcohol in semicontinuous or continuous mode in a catalyst-containing suitable reactor. In particular, the process according to the invention is used to prepare linalool from Geraniol and/or nerol.

Abstract: Continuous production of 5-alkoxy oxazoles (I) comprises heating an alkyl alpha-isocyanoalkanoate ester (II) at a temperature above 80 degreesC in the presence of an auxiliary agent and withdrawing the product from the reactor. Continuous production of 5-alkoxy oxazoles of formula (I) comprises heating an alkyl alpha-isocyanoalkanoate ester of formula (II) at a temperature above 80 degreesC in the presence of an auxiliary agent and withdrawing the product from the reactor. R1 = optionally substituted 1-6C alkyl; R2 = H or optionally substituted 1-6C alkyl. An Independent claim is also included for a process for producing pyridoxine derivatives of formula (IX), comprising: (1) converting an amino acid of formula (III) to an ester of formula (IV); (2) converting (IV) to a formamido ester of formula (IV); (3) converting (IV) to (II); (4) converting (II) to (I) as above; (5) reacting (I) with a protected diol of formula (VI) to form a Diels-Alder adduct of formula (VII); and (6) converting (VII) to (IX) by acid treatment and deprotection. R3, R4 = protecting groups or together form a protecting group.

Abstract: Alkali metal methoxides are prepared from aqueous alkali metal hydroxide, which may have been admixed with methanol, and methanol in a reaction column having at least 5, preferably from 15 to 30, theoretical plates between the feed point for the aqueous alkali metal hydroxide and the feed point for the methanol. The gaseous methanol/water mixture formed in the reaction is fractionated in a rectification column. In one variant of the invention, the trays chosen for the reaction column configured as a bubble cap tray, valve tray or sieve tray column are trays in which not more than 5%, preferably
