Title: Manufacture of adipic acid
Inventor: BRUNER JR HAROLD STANLEY
IPC: C07C51/10
Filed: 1997-10-06
Abstract: PURPOSE: A process for the manufacture of adipic acid is provided. CONSTITUTION: A process for the preparation of adipic acid from pentenoic acid or mixtures of pentenoic acid isomers comprises: (a) forming a reaction mixture containing the pentenoic acids or mixtures thereof, water, carbon monoxide, gamma-valerolactone, an iridium catalyst promoted with bromide or iodide and optionally a strong acid reaction promoter wherein the concentration of gamma-valerolactone is from 30 to 70% by weight of the reaction mixture; and (b) reacting the mixture to convert pentenoic acids or esters to adipic acid and branched six carbon dicarboxylic isomers of adipic acid. A strong acid reaction promoter may be used in the process of the present invention. The preferred acid promoter is selected from the group consisting of triflic, p-toluenesulfonic and phosphoric acid. The process of the present invention may be operated as a batch or a continuous process. As a continuous process, it is preferred to add subsequent to step (b) the steps: (c) removing a portion of the mixture as a product stream and recovering crude adipic acid and forming a by-product stream; (d) subjecting the by-product stream to dehydrocarboxylation to convert a part of the by-product branched six carbon dicarboxylic isomers of adipic acid to pentenoic acid isomers forming a recycle stream; and (e) combining the recycle stream and fresh feed to form the reaction mixture of step (a). The crude crystals of adipic acid recovered from the product stream of the present process are larger in size, easier to separate from the product stream and of higher purity than those produced by prior art processes.

Patent KR-20010005523-A (KR)
IPC: G02F1/025
Filed: 1998-02-24
Abstract: An optical device (300) comprises a multilayer structure, formed by wafer bonding, incorporating in sequence a silicon dioxide layer (304), a buried silicide layer (306), a contact layer (308) and a silicon surface layer (310). The surface layer (310) is selectively etched to form an exposed rib (312). An upper surface of the rib (312) is doped to form an elongate electrode (314) therealong. The surface layer (310) is selectively etched to the contact layer (308) in regions remote from the rib (312) to form via channels (316a, 316b) for making electrical connection to the contact layer (308). The rib (312) forms a waveguide along which radiation propagates. When the electrode (314) is biased relative to the contact layer (308), charge carriers are injected into the rib (312) and induce refractive index changes in a central region (324) thereof where most of the radiation propagates along the rib (312). The silicide layer (306) provides an efficient current conduction path for injecting the carriers, thereby providing enhanced device operating bandwidth and reduced power dissipation.
