    摘要： Pinitol is obtained from carob extracts by inversion of saccharose contained in the extracts to fructose and glucose to obtain a syrup, then subjecting the syrup to chromatographic separation by means of ion-exchange resins to obtain a solution of pinitol in water, and separating of the pinitol from said solution. The solution of pinitol in water preferably contains 90% or greater pinitol content. The ion-exchange resins may be strong cationic or strong anionic exchange resins.

    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： A process for the production of diisopropyl ether where acid is removed, without extraction, from the reactor effluent before being recycled to the reactor or being passed to downstream processing units has been developed. The process involves (1) reacting propylene and water to produce isopropyl alcohol in a reactor and reacting the isopropyl alcohol with propylene to produce diisopropyl ether in the presence of an acidic ion exchange resin catalyst to afford a reactor effluent stream containing at least water, isopropyl alcohol, diisopropyl ether, propylene, and acid, (2) passing the reactor effluent to an acid removal zone to produce an acid-depleted stream, (3) dividing the acid-depleted stream into two portions, and (4) recycling a portion to the reactor and collecting a portion.

    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.
