Abstract: A compound of the formula: ##STR1## wherein X is a hydrogen atom, a methyl group, a methoxy group or a chlorine atom, R.sub.1 is a C.sub.2 -C.sub.7 alkyl group or a C.sub.5 -C.sub.7 cycloalkyl group and R.sub.2 is a hydrogen atom, a halogen atom, a C.sub.1 -C.sub.4 alkyl group or a methoxy group, or when R.sub.1 and R.sub.2 are taken together, they represent a C.sub.4 -C.sub.6 alkylene group, provided that when R.sub.1 is a tertiary alkyl group, R.sub.2 does not represent a halogen atom, herbicidal compositions containing the above-mentioned compounds and methods for controlling weeds utilizing the same.
Abstract: N-alkynylanilides, a process for their preparation, fungicidal compositions containing the N-alkynylanilides as the active ingredient and methods for the use of such compounds or compositions for combatting plant fungi are disclosed.
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: 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.
