摘要： An ion exchange resin comprises a crosslinked resin and a salt covalently bonded to a carbon of the resin, wherein the salt comprises a first non-metallic cation and a first counteranion, wherein the first counteranion comprises a second non-metallic cation and a thiosulfate counteranion, and wherein the ion exchange resin is essentially free of metals. The ion exchange resin finds particular use in the removal of impurities from solutions that are useful in the manufacture of semiconductor devices.

摘要： The present invention is a cyclic process for the preparation of ethyl tert.-alkyl ethers by the reaction of an alcohol, ethanol, with an iso-olefin such as isobutylene or isoamylene wherein an effluent from the reaction zone is separated in a distillation column to provide an overhead effluent stream and a bottoms effluent stream comprising ethyl tert.-alkyl ether and unreacted ethanol. The unreacted ethanol is recovered in an adsorption zone comprising a selective adsorbent selected from the group consisting of zeolite 13X, sodium zeolite Y, alumina, silicalite and mixtures thereof. The invention is useful in recovering unreacted ethanol from the bottoms effluent stream and returning the unreacted ethanol to the reaction zone. The invention reduces the cost of this separation which is complicated by the formation of an azeotrope between the unreacted alcohol and the ether.

摘要： In a single stage process for producing diisopropyl ether, SO.sub.3 from a DIPE reactor effluent is transferred to an aqueous phase in a liquid extraction zone and removed from the aqueous phase using a basic ion exchange resin disposed in an SO.sub.3 removal zone. As a consequence, DIPE reactor effluent can be returned to the DIPE reactor to serve as a solvent and to assist in providing cooling to the DIPE reactor without causing catalyst deactivation.

摘要： The present invention is an improved process for the recovery of ethylene glycol from spent glycol generated in the manufacture of polyethylene terephthalate. The spent glycol typically consists of metal oxide catalyst residues, low molecular weight terephthalate oligomers, diethylene glycol and other trace impurities. The improved process of the present invention is based on the principle that elevating the temperature of the spent glycol increases the solubility of the low molecular weight oligomers so that the low molecular weight oligomers can be dissolved in the ethylene glycol and further that the spent glycol at an elevated temperature may be passed through an ion exchange bed to remove metal oxide catalysts, color forming impurities and other trace impurities.
