    Abstract: Copolymerisable oxime ethers of the general formula in which A is a divalent connecting link, R and R independently of one another are a C1- to C10-alkyl radical, a C1- to C10-alkoxy radical, a C5- to C10-cycloalkyl radical or a C5- to C10-aryl radical, which can also contain 1 - 3 non-adjacent nitrogen, oxygen or sulphur atoms as hetero atoms in the carbon chain or the carbon ring and can be substituted by one to three C1- to C4-alkyl or alkoxy groups, R or R can be a hydrogen atom or R and R together form a bridge of 3 to 14 carbon atoms, some of the carbon atoms also being able to be part of an aromatic ring, Z is an n-valent organic radical which contains a copolymerisable ethylenically unsaturated group, and n is an integer from 1 to 3.

    Abstract: In the proposed method of producing crystallised N-methylol-(meth)acrylamide from (meth)acrylamide and paraformaldehyde, the reaction of the solid reaction components to produce a molten product and subsequent crystallisation are carried out in a reactor vessel while mechanical shear stress is applied to the reaction mixture, preferably in a self-cleaning worm reactor or disc reactor. The reaction and crystallisation of the molten product take place preferably without any solvents being added. A catalyst, in particular an alkali carbonate or trialkyl amine, can be used for the reaction.

    Abstract: Unsaturated phenone derivatives of the general formula I I where R1 is C1-C4-alkyl, cyclopropyl, cyclopentyl, cyclohexyl, indanonyl, tetralonyl, phenyl or phenyl in which some or all of the hydrogen atoms have been replaced by a C1-C4-alkyl, C1-C4-alkoxy or C1-C4-thioalkyl group, or together with R2 or R6 forms an ethylene or propylene bridge, R2 to R6 are each hydrogen, C1-C4-alkyl, C1-C4-alkoxy or C1-C4-thioalkyl, and R3, R4 and R5 may each additionally be hydroxyl, R2 or R6 may additionally together with R1 form an ethylene or propylene bridge and one or more, but not more than three, of the radicals R2 to R6 are a group of the general formula II II or III III where K is C1-C10-alkylene which may contain 1 or 2 oxygen or sulfur atoms, Y is straight-chain or branched C1-C10-alkylene or is C1-C10-alkylene which is substituted by carboxyl, a carboxylate anion, an alkyl C1-C4-carboxylate group or hydroxyl, X is -NH- or -(N-Alkyl)- of 1 to 4 carbon atoms and Z is hydrogen or C1-C4-alkyl.

    Abstract: The invention relates to dihydroxy compounds which are attached to ester groups and have reduced reactivity and the formula I in which R is a linear or branched alkylene radical with 2 to 20 C atoms, an optionally substituted cycloalkylene radical with 5 to 10 carbon atoms, or a polyoxyalkylene radical composed of 2 to 50 oxyalkyl groups which are linked blockwise or in random distribution and have 2 to 4 C atoms in the alkylene radical. The dihydroxy compounds are prepared by transesterification of alkyl hydroxypivalates with alkanediols, cycloalkanediols or polyoxyalkylene glycols and are used in polyurethane chemistry.

    Abstract: Process for the preparation of 3-aryl-isobutanols of the general formula I … … in which… R and R are hydrogen or an alkyl or cycloalkyl radical with up to 8 C atoms, preferably an alkyl radical with 1 to 4 C atoms,… which is characterised in that arylcarbinols of the general formula II … … are reacted with n-propanol in the presence of catalytic amounts of an alkali metal hydroxide or alkali metal oxide at 250 to 350 DEG C in a closed reaction vessel. … The process is particularly important for preparing 3-aryl-isobutanols of the formula I in which R is an alkyl radical with 1 to 4 C atoms and R is hydrogen. The p-methyl-, p-isopropyl- and p-tert.-butylphenylisobutanols obtained in this way in very high selectivity are valuable precursors for the fragrances jasmorange, cyclamenaldehyde and Lysmeral (Lilial ) which are in high demand.
