There is described the use of substituted N-trichloromethyl thiodicarboximides in combination with N,N'-substituted bis-(2,4-diamino-s-triazin-6-yl)-oligosulfides in vulcanizable rubber mixtures in order to improve the vulcanization characteristics and such rubber mixtures.

Substituted N-trichloromethyl thiodicarboximides and N,N-substituted

The invention is directed to bis-(2-ethylamino-4-diethylamino-s-triazine-6-yl)-tetrasulfide and a process for its production from the corresponding mercaptotriazine. The compound of the invention is employed in vulcanizable mixtures as a cross-linker or as vulcanization accelerator.

Bis-(2-ethylamino-4-diethylamino-s-triazine-6-yl) tetrasulfide, process

The invention is directed to vulcanizable halogen rubber mixtures which contain 2-sec.amino-4,6-dimercapto-s-triazine, silica, and optionally carbon black.

Vulcanizable 2-sec.amino-4,6-dimercapto-s-triazine containing halogen

The invention is directed to bis-(2-ethylamino-4-diethylamino-s-triazin-6-yl)-tetrasulfide and a process for its production from the corresponding mercaptotriazine. The compound of the invention is employed in vulcanizable mixtures as a cross-linker or as vulcanization accelerator.

Vulcanizable mixture containing

There are prepared 1-amino-2-mercapto-2-methylpropyl phosphonic acid or 1-amino-2-mercapto-2-methylpropyl alkylphosphinic acids of the formula ##STR1## in which Y is hydroxy or an alkyl group by reacting thiazoline-(3) with a phosphonic acid dialkyl ester or an alkylphosphinic acid alkyl ester and then hydrolytically splitting the thiazolidinyl phosphonic acid dialkyl ester or thiazolidinyl alkylphosphinic acid alkyl ester. The thiazolidinyl compounds are new compounds. The 1-amino-2-mercapto-2-methylpropyl phosphonic acid and the 1-amino-2-mercapto-2-methylpropyl alkylphosphinic acids are needed for pharmaceutical purposes.

Process for the production of substituted phosphonic and phosphinic

.gamma.-chlorocarboxylic acid methyl or ethyl esters are cyclized to the corresponding cyclopropane carboxylic acid esters by employing the sodium or potassium alcoholate of methanol or ethanol in the presence of the same alcohol at a temperature above the boiling point of the alcohol employed.

Process for cyclizing upsilon-chlorocarboxylic acids

There are prepared compounds of the general formula ##STR1## where R is methyl or ethyl and R.sub.1 is halogen or hydrogen. The compounds are useful as fungicides, especially against Piricularia oryzae on rice.

Fungicidally active benzhydrol derivatives

Herbicidally active derivatives of the formula ##STR1## in which R represents methyl, ethyl or n-propyl.

Herbicidally active 1,2,4-triazin-5-one derivatives

1-Methyl-2-chlorocyclopropanecarboxylic acid and its lower esters are produced by the selective hydrogenating dechlorination of the corresponding 1-methyl-2,2-dichlorocyclopropane compounds. The new materials can be used as intermediate products for the production of pesticides and medicines.

1-Methyl-2-chlorocyclopropanecarboxylic acid and its ester

There are prepared new cyclopropane carboxylic acid esters, particularly the tetrahydrobenzyl ester. They have insecticide and ovicide activity. The compounds are prepared by known methods of esterification.

Cyclopropane carboxylic acid and process for their production and use

Aliphatic, cycloaliphatic and aromatic epoxides are reacted with ketone cyanohydrins of the formula ##STR1## wherein R.sub.1 and R.sub.2 are aliphatic groups of 1 to 4 carbon atoms at 20.degree. to 150.degree. C. to produce hydroxynitriles. The reaction optionally can be carried out in an inert organic solvent.
