Abstract: Disclosed are new azo dyes prepared by diazotizing selected substituted anilines and coupling with aniline couplers containing sulfate ester groups. These dyes impart fast yellow to reddish-orange shades on polyamide fibers and also color cellulose acetate and wool. The dyes have the following general formula: ##STR1## wherein R is selected from a variety of groups such as alkyl, alkoxy, aryl, cycloalkyl, aryloxy, NH.sub.2, and NH alkyl; X is hydrogen, halogen, alkyl, or the like; Y is hydrogen or halogen; R.sub.1 is selected from groups such as hydrogen, alkyl, alkoxy, halogen, acylamido, alkylthio, and aryloxy; R.sub.2 is selected from such groups as hydrogen, alkyl, aryl and cycloalkyl; Z is a linking group such as alkylene; M is H.sup.+, Na.sup.+, K.sup.+, or NH.sub.4.sup.+ ; and m is 0, 1, or 2.

Abstract: N-alkylated aromatic amines are produced by reductively alkylating an aromatic amine with pressurized hydrogen in the presence of a ketone, a noble metal catalyst and a promoter acid having a pKa between 0.3 and 1.5.

Abstract: 2-Aryl-1,3-cyclohexanedione compounds and their alkali metal and ammonium salts exhibit outstanding herbicidal, miticidal and mite ovicidal activity.

Abstract: Substituted tetrahydro-1H-1,4-diazepino[1,7-a]benzimidazoles of the formula: ##STR1## and pharmaceutically acceptable salts thereof having thereapeutic activity as analgesic agents.

Abstract: Aromatic amines are obtained in high yield and purity by treating the corresponding cyclohex-2-en-1-on-oxime hydrochlorides with the at least threefold molar amount of acetic anhydride.

Abstract: This invention relates to compounds having the formula ##STR1## in which R.sub.F is a perfluoro radical C.sub.n F.sub.2n+1 with n=1-20, and R is a C.sub.1-20 alkyl radical, a C.sub.4-15 cycloalkyl radical, a C.sub.5-20 cycloalkyl-alkyl radical, or a C.sub.6-20 aromatic radical.Said compounds constitute valuable intermediates for the synthesis of surface-active agents.

Abstract: The present invention relates to certain ring-fluorinated 4-(hexadecyl-amino) N-substituted benzamide compounds as hypolipidemic and antiatherosclerotic agents together with their pharmacologically acceptable acid-addition and cationic salts. The amino functions of the benzamide groups are selected from the groups consisting of loweralkanesulfonylamino, phenylsulfonylamino, loweralkanoylamino, benzoylamino and carboxyalkylamino.

Abstract: Non-ionic polyiodo saccharidic ether substituted anilines are provided as contrast media, the ether being non-glycosidyl. The compounds have excellent physical properties in having acceptable water solubility or capable of stable suspension, relatively low osmotic pressure, good thermal stability, so as to be heat sterilizable, and a high iodine proportion. The compounds can be prepared from polynitroaromatics by substitution and reduction.

Abstract: A process for preparing bentotrifluoride or its derivatives by contacting benzotrichloride or its derivatives corresponding thereto with hydrogen fluoride in a gaseous phase, characterized in that the contact is carried out in the presence of aluminum fluoride and, if desired, of chlorine.
