  • Patent number: 10442830
    Abstract: A process for obtaining a mixture of C4-C8 and C9-C18 alkyl monoether of saccharide, comprising: a) a first step of acetalization or trans-acetalization of a saccharide or of a mixture of saccharides with a C4-C8 aliphatic aldehyde or the acetal thereof, b) a second consecutive or simultaneous step of acetalization or trans-acetalization of the product obtained in a) of the saccharide or mixture of saccharides with a C9-C18 aliphatic aldehyde or the acetal thereof, c) a step of catalytic hydrogenolysis of the saccharide acetals obtained, and d) a step of recovery of a mixture of C4-C8 and C9-C18 alkyl saccharide monoethers. The invention further relates to a mixture of C4-C8 and C9-C18 alkyl saccharide monoethers and the use thereof as a surfactant.

  • Patent number: 10191280
    Abstract: A glazing for information display includes an assembly of two transparent inorganic or plastic sheets, connected together by a thermoplastic or adhesive interlayer or by multilayer sheets incorporating the interlayer, wherein a luminophore material is incorporated to enable the display. One of the luminophores includes a benzene ring substituted at least by: a first ester —COOR group, wherein R is a linear or branched carbon-based group including a main carbon-based chain of at least six consecutive carbon atoms, the R group including, if the chain is linear, more than 10 carbon atoms and, if the chain is branched, at least 7 carbon atoms, optionally a second —COOR? group, wherein R? is another hydrocarbon-based group or hydrogen, the second group optionally being in para position on the benzene ring with respect to the first ester group, two hydroxyl —OH groups that are optionally in para position on the benzene ring.
