Abstract: Disclosed is a process for the preparation of aliphatic carbonyl compounds selected from aliphatic carboxylic acids, alkyl esters of aliphatic carboxylic acids and anhydrides of aliphatic carboxylic acids by the carbonylation of olefins in the presence of a catalyst system comprising (1) a primary component selected from at least one Group 6 metal, i.e., chromium, molybdenum, and/or tungsten and (2) a secondary component selected from at least one of certain halides and tertiary and quaternary compounds of a Group 15 element, i.e., nitrogen, phosphorus and/or arsenic. The process is carried out in the absence of metals of groups 8, 9, and 10 (Fe, Rn, Os, Co, Rh, In, Ni, Pd, and Pt) and of formic acids and format esters. The process constitutes an improvement over known processes since it can be carried out at moderate carbonylation conditions without the necessity of using an expensive noble metal catalyst, volatile, toxic materials such as nickel tetracarbonyl, formic acid or a formate ester.

Abstract: This invention relates to a process for recycling waste material selected from amino-carboxylic acid oligomers or polymers and amido-carboxylic acid oligomers or polymers into amido-carboxylic acids. A mixture containing water, an oligomeric or polymeric waste material, and a carboxylic acid is heated. The mixture is cooled to obtain a two phase system containing an aqueous phase and an organic phase which are separated. Carboxylic acids, unreacted starting materials, and the monomeric amido-carboxylic acid product are distilled from the organic phase. The remaining solid residue composed of high boiling oligomeric amino-carboxylic acids is recycled into Step (A).

Abstract: Disclosed are fibrous structures comprised of shaped fibers wherein the thickness of the compressed fibrous structure at 1.00 psi (70.3 g/cm ) is >/=1.4 times that of a similar compressed structure having the same area density and made from round cross section fibers of the same dpf as the shaped fibers. The invention is useful in articles such as coats, gloves, boats, shoes, etc. made using the structures disclosed herein. The surprising feature of structures according to the present invention is the thickness retention at high pressures. This retained thickness under pressure translates directly into decreased heat transfer or improved insulation.
