Title: Process for manufacturing a dmt itermediate product of given purity and subsequent processing thereof to obtain ultrapure dmt and/or medium-or high-purity terephthalic acid
Inventor: KORTE HERMANN-JOSEPH
IPC: C07C69/82
Filed: 1990-02-13
Abstract: ABSTRACT      The invention relates to a process  for the production of a DMT intermediate product as well as its working up to fibregrade DMT and to medium pure and pure terephthalic acid.  The DMT intermediate product is moreover produced by combined oxidation of a predominantly para-xylene (p-X) and para-toluic acid methyl ester (p-TE) containing mixture in liquid phase with an oxygen containing gas, esterification of the acids being produced with methanol, distillative or rectificative separation of the esterification products being produced into a p-TE rich fraction I, a fraction II containing more than 99% by weight DMT and its isomers and a high boiling residue fraction III as well as feeding back the p-TE fraction I into the oxidation, with the residue fraction III having a DMT content of 15 to 70% by weight and the DMT fraction II being purified by single solvent recrystallisation in methanol to form the DMT intermediate product to such an extent that the amounts of hydroxymethylbenzoic acid methyl ester (HM-BME) and terephthalic acid methyl ester (TAE) in the DMT intermediate product amount together to less than 200 ppm.      The working up of the DMT intermediate product to fibregrade DMT takes place by a second recrystallisation, the working up to terephthalic acid by washing of the DMT intermediate product in methanol, hydrolysis, crystallising out and possibly subsequent washing in water.

Patent CA-2052539-A1 (CA)
Inventor: GRINSTEINER JAMES J
IPC: F04B23/08
Filed: 1991-09-30
Abstract: A tandem fuel  pump assembly  for  internal  combustion engines includes a housing having a fixed spring retainer mounted thereinside which supports a diaphragm pump biassing spring thereabove to force a diaphragm defining the movable lower wall of a first pumping chamber to reduce the volume thereof and eject fuel  from an outlet thereof preferably through  a  fuel  filter  to  the inlet  of  a  second piston pumping chamber. A second biassing spring supported below the spring retainer forces a pumping piston downwardly to reduce the volume of the second pumping chamber and thereby eject fuel therefrom to an engine fuel rail for injection into the engine therefrom.  The  diaphragm and piston are mechanically connected by a pump stem through a lost motion connection to accommodate differing pumping strokes of the two pumps, so that a single tappet actuated by the engine camshaft mechanically raises the piston to cause movement thereof to fill the second piston pump chamber while the biassing  spring  of  the  piston  pump pulls  the  diaphragm through the stem against the action of its biasing spring to fill  the first chamber during the pumping  stroke of  the piston pump.

Title: High purity aromatic polyester, a film and other products and devices containing such polyester as well as a process for preparing such film
Inventor: FIALLA PETER
IPC: G11B5/73
Filed: 1991-08-28
Abstract: A high purety aromatic polyester consisting essentially of repeating interpolymerized units derived from 1,1-bis(4hydroxyphenyl)-1-phenylethane and 9,9-bis(4-hydroxyphenyl)fluorene and isophthalic acid choride and/or terephthalic acid chloride, which polyster contains less than 4 % by weight of low molecular weight species of a molecular weight less than 8000 and forms films having an elongation at break of at least 50. These polyesters are prepared by a novel interfacial polymerization process whereby the ratio of the low molecular weight species is further reduced during the precipitation of the polymer using e.g. MEK or acetone as precipitant. The polyesters have excellent tensile strength and elongation, chemical resistance, moisture resistance, temperature resistance, electrical properties such as high volume resistivity, high surface resistivity, high tracking and arc resistance, high dielectric constant, high dielectric strength and low dissipation factor. The polyester can advantageously be used as a film or as a layer deposited onto a substrate. It can be e.g. used as electrical insulator, as dielectric medium especially in a film wound capacitor and as optical medium in optical fibers.
