Abstract: The invention provides novel mepiquat plant growth regulator compositions which have improved hygroscopicity and corrosion characteristics. The novel mepiquat plant growth regulator compositions of the invention can be readily prepared from technical mepiquat chlorid inter alia by electrochemical ion exchange processes or by quaternization of N-methylpiperidine with dimethylcarbonate as starting material.

Abstract: Zemedelsky úcinný prostredek, který obsahuje slouceniny obecného vzorce I, kde symboly DMP, M, B, O, A, m a n mají specifický význam. Zpusob regulace rustu rostlin, který spocívá v nanesení prostredku obsahujícího slouceninu vzorce I na rostliny. Prostredky k regulaci rustu rostlin obsahující slouceninu vzorce I se snadno pripravují z technického mepiguátchloridu zpusobem založeným na elektrochemické výmene iontu nebo kvarternizací za použití N-methylpiperidinu a dimethylkarbonátu jako výchozích látek.

Abstract: A method for the production of 3-hydroxy-3-methyl-penta-1,4-dienyl-substituted oxo-cyclohexane or oxo-cyclohexene derivatives involves cathodic reduction of the corresponding 3-hydroxy-3-methyl-pent-4-en-1-ynyl derivative in a split or quasi-split electrolytic cell at pH 2-9. A method for the production of compounds of formula (I) or (I') involves the cathodic reduction of compounds of formula (II) in a split or quasi-split electrolytic cell at pH 2-9. R = oxo-cyclohexyl or oxy-cyclohexenyl (both optionally substituted with hydroxyl, alkoxy and/or alkyl groups), the oxo groups being in the form of an acetal, ketone or enol ether; R = a hydroxyl group or a protecting group which can converted into OH by hydrolysis. An Independent claim is also included for an electrolytic cell for use in this process in which the working electrode is made of solid graphite, sheets of graphite felt or carbon felt, woven fabric with carbon-coated electrolyte-contact surfaces, carbon-filled porous solids, or porous metal.

Abstract: Methods of preparing or purifying onium hydroxides of the elements N, S or P by electrodialysis involve an electrodialysis apparatus comprising one or more cell units, each cell unit comprising a bipolar membrane and an anion-selective membrane, and a bipolar membrane or a cation-selective membrane being located on the anode side between the last anion-selective membrane and the anode.
