摘要:
According to the invention, .alpha.-chloracetoacetamides, which is to be understood as including both .alpha.-chloro-N-monoalkylacetoacetamides and .alpha.-chloro-N,N-dialkylacetoacetamides, the alkyl radicals of which contain 1 to 3 carbon atoms, are produced by reacting the corresponding acetoacetamides with chlorine in aqueous solution at temperatures in the range of from -1.degree. C. to -25.degree. C. At a conversion of at least 95%, a selectivity of at least 97% and a yield of at least 95% of the theoretical yield, calculated on reacted acetoacetamide, are obtained.

摘要:
N-cyclohexyl-formamide is reacted with sulfur monochloride in the presence of an organic hydrogen chloride acceptor to form N,N'-di(cyclohexyl)-N,N'-dithiobis(formamide), which can then be reacted with sulfuryl chloride or chlorine to form N-chlorothio-N-cyclohexyl-formamide which can then be reacted with an olefin to form a retarder having the following structural formula. ##STR1##
摘要:
This invention relates to triiodized dicarboxylic acid anilides containing radioactive iodine of the formula ##SPC1##WhereinR.sub.1 is hydrogen, carboxyl, N-acylamino, N-acylaminomethyl, N-alkyl-N-acylamino, N-butyrolactamyl, or an ##EQU1## group, wherein R.sub.3 and R.sub.4 are each hydrogen, lower alkyl or hydroxyalkyl, or R.sub.3 and R.sub.4 together with the nitrogen atom form a 5 to 7 member heterocyclic ring which can contain a further oxygen, nitrogen or sulfur hetero atom;R.sub.2 is hydrogen, lower alkyl or hydroxyalkyl; andX is straight-chain or branched alkylene of 1-14 carbon atoms, which can be interrupted by one or more oxygen or sulfur atoms,As well as the physiologically acceptable salts thereof with suitable bases. These compounds are especially useful in the preparation of radioactive functional diagnostic agents.
IN WHICH R, R1, m, n, p and q have the measuring given below in the disclosure and a process for their manufacture. The polyamines are useful as textile plasticisers for synthetic fibres, preferably polyacrylonitrile fibre materials.

摘要:
A number of new quaternary ammonium salts of n-substituted palmitamides have been prepared by conventional methods. These derivatives have been characterized by exhibiting antimycotic activity and three of the derivatives, 4-palmitoyl-1,1dimethylpiperazinium iodide, (2palmitoylaminoethyl)trimethylammonium iodide, and 4-palmitoyl-1methyl-1-(1,4,5,6,7,7-hexachlorobicyclo(2.2.1)-hepta-2,5-diene -2methylene)piperazinium bromide have been further characterized by exhibiting nematocidal activity.
