  • Patent number: 7074872
    Abstract: Disclosed is a process for modifying cashew nut shell liquid (CNSL) which involves the steps of subjecting the CNSL to ozonolysis to form ozonolysis reaction products, followed by reduction of the ozonolysis reaction products to give a mixture of phenolic components and aldehydes. In a preferred embodiment, the process involves reacting CNSL with ozone to form a mixture containing ozonolysis reaction products, and then treating the mixture under reducing conditions to form a further mixture containing phenolic components with an eight carbon chain having a terminal —CHO group and alkyl components of varying lengths with either one or two terminal —CHO groups. The resulting CNSL aldehydes may be used to form adhesives for use in the manufacture of composites such as wood particle board.

  • Publication number: 20050010069
    Abstract: Ozonolysis is a well known process involving reacting ozone with alkene compounds, for example in unsaturated vegetable oils or free fatty acids and esters thereof, to form ozonolysis products (e.g. ozonides). The invention concerns ozonolysis of unsaturated oils (e.g. unsaturated plant oils and/or unsaturated animal oils) in the presence of a participating co-reactant to form reaction products particularly suitable for use in the formation of resins.

  • Patent number: 6768029
    Abstract: The invention provides a solid composite material comprising a matrix formed from a particulate or fibrous material and a cured thermosetting resin, wherein the cured thermosetting resin is derived from an oxidative cleavage product selected from aldehydes and peroxides and mixtures thereof formed by the oxidative cleavage of an unsaturated bond in an unsaturated plant or animal oil, other than the ozonolysis cleavage product of cashew nut shell liquid. Also provided is a process for the production of aldehydes and/or peroxides, which process comprises the treatment of a vegetable oil with ozone (e.g. in the presence of an alcohol as a solvent for the oil) so that hydroperoxides are produced, and the reductive cleavages of the hydroperoxides with a reducing sugar.
