Preparation of aliphatic N,N-dialkyl-substituted amino alcohols

N-substituted cyclic amines of the general formula I ##STR1## where A is an alkylene group or a --(CH.sub.2).sub.n --[--O--(CH.sub.2).sub.m ].sub.r group which may be monosubstituted or polysubstituted by radicals R without the radicals R in a defined compound having to be identical, R is alkyl, alkoxyalkyl, unsubstituted or alkyl-substituted or alkoxy-substituted cycloalkyl, cycloalkylalkyl, aryl or arylalkyl, n and m independently of one another are each from 2 to 8 and r is from 1 to 3, the --(CH.sub.2).sub.n --[O--(CH.sub.2).sub.m ].sub.r group consisting of from 5 to 12 members, are prepared by reacting a primary amine of the general formula II

Preparation of N-substituted cyclic amines

A process for the preparation of tertiary alkylamines having a total of up to 9 carbon atoms by reacting a dialkylamine with a C.sub.2 -C.sub.4 -alcohol in the presence of a hydrogenation/dehydrogenation catalyst which contains essentially only copper as the hydrogenating/dehydrogenating catalytic metal is proposed, wherein the reactants

Preparation of trialkylamines

Trialkylamines are prepared by reacting primary alcohols with ammonia or a primary alkylamine in the presence of a hydrogenation/dehydrogenation catalyst and in the presence of hydrogen by

Zineb is stabilized by mixing it with calcium oxide in the absence of sulfur.

Stabilization of zineb

4-(m,m'-ditert.-butyl-p-hydroxyphenyl)-butan-2-ones are produced by reaction of a 4-hydroxybutanone-(2) with 2,6-ditert.-butylphenol in the presence of a strong acid at elevated temperature. The compounds obtainable by the process, particularly 4-(m,m'-ditert.-butyl-p-hydroxyphenyl)-butane-2-one, are starting materials for the production of dyes, pest control agents and plastics auxiliaries and particularly of stabilizers for polyolefins and polyamides.

Production of 4-(m,m'-ditert.-butyl-p-hydroxyphenyl)-butan-2-ones

Amidosulfonic acids are manufactured by reacting ureas first with sulfur trioxide and then with sulfuric acid in the presence of organic solvents. The products are sweeteners, in particular cyclohexylamidosulfonic acid and its calcium, sodium and potassium salts, and starting materials for the manufacture of sweeteners, dyes and pesticides.

Manufacture of amidosulfonic acids

Novel 4-(m,m'-di-t-butyl-p-hydroxyphenyl)-butyl-2 compounds which are intermediates in the manufacture of dyes, pesticides and plastics auxiliaries, particularly stabilizers for polyolefins and polyamides. When molten, they form specific solvents for alkylphenols and are perfumes or form ingredients of perfume compositions having a fruity odor.

4-M,M'-Di-t-butyl-p-hydroxyphenyl) butyl-2 compounds

Novel 4-(m,m'-di-t-butyl-p-hydroxyphenyl)-butyl-2 diamides of aliphatic, araliphatic, cycloaliphatic or aromatic dicarboxylic acids which are intermediates in the manufacture of dyes, pesticides and plastics auxiliaries, particularly stabilizers for polyolefins and polyamides. When molten, they form specific solvents for alkylphenols and are perfumes or form ingredients of perfume compositions having a fruity odor.

4-(M,M'-Di-t-butyl-p-hydroxyphenyl)-butyl-2-diamides

A process for the production of high molecular weight .alpha.,.beta.-unsaturated aldehydes by alkylation of the .gamma.-carbon atom of a lower molecular weight .alpha.,.beta.-unsaturated aldehyde with a substituted allyl alcohol which has a chain branching in the 3-position carbon atom or a phenyl radical in the 3-position or of a corresponding allyl alcohol carboxylic ester at elevated temperature in the liquid phase. The products are valuable intermediates for the production of natural substances and odorants.

Production of high molecular weight .alpha.,.beta.-unsaturated aldehydes

4-(M,M'-DI-T-BUTYL-P-HYDROXYPHENYL) BUTYL-2 COMPOUNDS

New and valuable herbicide based on 1-phenyl-4-amino-5-chloro (or -5-bromo)-pyridazone-(6) in the form of an aqueous suspension.

Herbicides

A process for the production of high molecular weight .alpha.,.beta.-unsaturated aldehydes by alkylation of the .gamma.-carbon atom of a lower molecular weight .alpha.,.beta.-unsaturated aldehyde with a substituted allyl alcohol which has a chain branching in the 4-position carbon atom or a phenyl radical in the 4-position or of a corresponding allyl alcohol carboxylic ester at elevated temperature in the liquid phase. The products are valuable intermediates for the production of natural substances and odorants.

A process for the production of .alpha.,.beta.-unsaturated ketones by reaction of an aldehyde with a ketone in the presence of a catalyst consisting essentially of zinc oxide in the liquid phase. The ketones obtained are suitable in some cases as solvents and in some cases as intermediates for the production of valuable odorants, dyes, plastics and especially natural substances.
