Abstract: The invention relates to a simple, cost-effective and eco-friendly process of recovering one or more cannabinoids from complex natural products, especially cannabidiol (CBD) and/or cannabidiolic acid (CBDA) from raw Cannabis plant material or extracts thereof.

Abstract: A process for preparing dialkyl terephalate comprising the following steps:—i) providing furan-2,5-dicarboxylate; ii) esterifying the furan-2,5-dicarboxylate with alcohol to form furan-2,5-carboxylic acid dialkyl ester; iii) reacting the furan-2,5-carboxylic acid dialkyl ester with ethylene under Diels Alder conditions, elevated temperature and pressure and in the presence of a catalyst such that dialkyl terephthalate is produced; wherein the Diels-Alder reaction is free from solvent; wherein the catalyst comprises a clay comprising metal ions and having Lewis acidity.

Abstract: A glyceride compound comprising a first aliphatic group and a first substituent group bonded to said first aliphatic group. The first substituent group has the formula —O(CH2CH2O)nP where n is 1 to 14 and P is a polymerisable group. An aqueous emulsion of the glyceride can be used in an emulsion polymerisation reaction to yield a polymer resin, which can then be mixed with a suitable base material, such as wood strands, to produce a composite material, such as Oriented Strand Board.
