摘要： A substituted benzene derivative is prepared in a process, which includes reacting a furan derivative of formula (I): wherein R is an alkyl group, with an olefin of formula (II): R1—CH═CH—R2 (II) wherein R1 and R2 are the same or different and independently are selected from the group consisting of hydrogen, —CN, —CHO and —COOR3, wherein R3 is selected from hydrogen or an alkyl group, or R1 and R2 together form a —C(O)—O—(O)C— group, with the proviso that R1 and R2 are not both hydrogen, to produce a bicyclic ether; and dehydrating the bicyclic ether to obtain a benzene derivative. The benzene derivative thus obtained can suitably be converted to a benzene carboxylic acid compound by oxidation.

摘要： Composition including a first component, including furfuryl alcohol and humins and a second component including an acidic polymerization initiator. The composition can be oligomerized to a resin, which has a viscosity in the range of 0.1 to 10,000 Pa·s at 25° C., determined according to ISO3219. The resin, or a blend of furfuryl alcohol and humins as a component A and an acidic polymerization initiator as a component B, separated from each other, may form a kit for an adhesive or impregnation agent.
