    摘要： Mono- and dithioic esters, the alcohol residue of which carries a group including one or more oxygen atoms, are prepared by the action of an oxygen-containing organic compound, carrying an active atom, upon a mixed magnesium salt of a mono- or dithioic acid, ##STR1## where Y is O or S, R is a hydrocarbon group and X is a halogen. The product obtained is treated with an aqueous acid. The new products so synthesized are of the type ##STR2## notably those where R' is a chain, --(CH.sub.2).sub.n --, with n=1 to 12, Z being --OH or --COOH and are used as a collector in the flotation of minerals.

    摘要： Enzymes are fixed on carriers with a bis-dithioester capable of combining with the enzyme and with the carrier. The bis-dithioester has at each of its ends a group capable of reacting with an aimine function. The enzyme may be contacted with the bis-dithioester before the enzyme and carrier are combined. The carrier is an inorganic or organic solid.

    摘要： The present invention relates to a process for the preparation of beads of copolymers bearing reactive groups, by polymerization in suspension in a non-aqueous medium. According to the invention a free radical polymerization is effected of at least two unsaturated monomers, of which one is the carrier of a reactive group such as acid chloride, alkyl chloride, alkyl dithiobenzoate or carboxyalkyl, in a medium composed of two emulsified, immiscible organic liquids, to form beads of chemically reactive copolymers.
