  • Publication number: 20120330032
    Abstract: A process for making a cyclic compounds such as cyclic acetal or cyclic ketones by feeding aldehyde or ketone compounds and polyhydroxyl compounds to a reaction zone at a molar ratio of polyhydroxyl compounds to aldehyde or ketone compounds of at least 3:1, reacting these compounds in the presence of a solid acid such as an acidic ion exchange resin, to generate a liquid reaction mixture without separating water from the reaction mixture as it is being formed in the reaction mixture, withdrawing the liquid reaction mixture from the reaction zone as a liquid product stream, and feeding the liquid reaction product stream to a distillation column to separate cyclic acetal compounds from unreacted polyhydroxyl compounds, and optionally recycling back the unreacted polyhydroxyl compounds to the reaction zone. The process produces cyclic acetal compounds in yields of at least 90% with long catalyst life. The process is also suitable to make cyclic ketals from ketone compounds.

A compound disclosed by the invention comprises an anionic portion combined with at least one cationic portion M+m in sufficient numbers to ensure overall electronic neutrality. The anionic portion is comprised of one of the groups (A) and (B): wherein Y1, Y2, Y3, Y4 and Y5 represent a carbonyl group, a sulfonyl group, a thiocarbonyl group, a thionyl group, a —C(═NCN)— or a —C(═C(CN)2)— group; Z represents an electroattractive radical; each of the substituents, RA, RB, RC and RD represents independently of one another a monovalent or divalent organic radical or is part of a polymer chain, with at least one of the substituents RC and RD being a perfluorinated radical. The compounds can be used especially for ionic conducting materials, electronic conducting materials, colorants, and the catalysis of various chemical reactions.

  • Patent number: 5808110
    Abstract: A transportable, storage stable cyclic ketone peroxide composition which comprises 1.0-90% by weight of one or more cyclic ketone peroxides and 10-99% by weight of one or more diluents selected from the group consisting of liquid phlegmatizers for the cyclic ketone peroxides, plasticizers, solid polymeric carriers, inorganic supports, organic peroxides and mixtures thereof, is disclosed. Also disclosed is the use of these cyclic ketone peroxide formulations in the modification of (co)polymers. These formulations provide a surprising degree of polymer modification when compared to their non-cyclic ketone peroxide counterparts.
