Abstract: The invention concerns a method for the preparation of polyoxyalkylene compounds wherein each compound has one primary amine group and one primary hydroxyl group. The method comprises alkoxylating a t-butyl ethylene, propylene or butylene glycol then aminating the product. Finally the t-butyl group is cleaved by an acid. The compounds of the method of this invention are useful in urethane/urea plastics including foams, elastomers and coatings.

Abstract: The invention relates to a compound of formula ##STR1## in which: X denotes a branched or unbranched alkylene radical containing 2 to 6 carbon atoms, optionally being able to be substituted with one or more hydroxyl radicals;R denotes a hydrogen atom, an alkyl or a mono- or polyhydroxyalkyl radical or an aminoalkyl radical in which the amine group can be mono- or disubstituted with an alkyl radical or with a mono- or polyhydroxyalkyl radical, the nitrogen atom also being able to form part of a heterocyclic system and the alkyl radicals containing 1 to 4 carbon atoms;R' denotes a hydrogen atom or a C.sub.1 to C.sub.4 alkyl radical;Y and Z denote a nitro and/or --NHR.sub.1 radical, R.sub.

Abstract: Process for the production of modified triglycerides which contain epoxide groups, secondary hydroxyl groups and ether groups. The invention particularly relates to the production of reaction products of epoxidized triglycerides, for example epoxidized soy oil, with polyfunctional alcohols, for example glycols. The products so prepared are valuable starting materials, particularly for the production of alkyd resins.

Abstract: A process for producing an alkylene oxide or mixture of alkylene oxides by a reaction which comprises reacting an alkane or alkylaromatic compound mixture thereof with an oxygen-containing gas in the presence of at least one molten nitrate salt catalyst.

Abstract: A process for the hydrogenation of C.sub.4 to C.sub.12 nitriles using a Raney cobalt catalyst promoted with chromium in which the catalyst activity is maintained by the addition of water. The process is particularly attractive to produce diamines by the hydrogenation of dinitriles.

Abstract: The present invention relates to novel 23-imino derivatives of C-076 wherein the C-076 compounds are not substituted at the 13-position. The C-076 compounds (collectively) are isolates from the fermentation broth of Streptomyces avermitilis. The precursor 23-oxo compounds are prepared by selectively oxidizing suitably protected 13-deoxy C-076 aglycone compounds by using oxidizing agents. Subsequently, the 23-oxo compounds are converted to the 23-imino compounds. These novel compounds have potent anthelmintic, insecticidal, ectoparasticidal, nematicidal and acaricidal activity. Compositions containing these 23-oxo and 23-imino derivatives of 13-deoxy C-076 aglycones also are described herein.

Abstract: Novel and useful silylenol intermediates for preparing penem and carbapenem antibacterials and a process for making selected intermediates are disclosed.

Abstract: Epoxy group-containing organic silicon compounds represented by general formula (I): ##STR1## wherein R, which may be the same or different, each represents a monovalent hydrocarbon group free from an aliphatic unsaturated bond; a represents 1 or 2; and n represents an integer of 2 to 6. The epoxy-containing organic silicon compounds contain no hydrolyzable group therein and are suited for use in coupling of organic compounds and modification or crosslinking of polymers.

Abstract: A series of novel, macrocyclic polyether compounds. The macrocycles have a 21-membered ring, containing six oxygen atoms, and they have a carboxy group (or a salt thereof) directed towards the interior of the ring. Administration of the compounds of the invention to ruminant animals (e.g. cattle and sheep) modifies their digestive fermentation processes such that the volatile fatty acids produced in the rumen contain a higher proportion of propionates rather than acetates, thereby increasing the efficiency of feed utilization in said ruminant animals. Additionally, the compounds of the invention show antibacterial activity in vitro against certain gram-positive microorganisms.
