BISPHENOL COMPOSITION AND POLYCARBONATE RESIN
A bisphenol composition including 95% or more by mass of a bisphenol, wherein a bisphenol represented by the following general formula (II) in the bisphenol composition constitutes 150 mass ppm or more, and the bisphenol composition has a methanol dissolution color (Hazen color number) of 2 or less,
##STR00001##
In formula (II), X denotes a single bond, —CR.sup.11R.sup.12—, —O—, —CO—, —S—, —SO—, or —SO.sub.2—, R.sup.11 and R.sup.12 independently denote a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, and R.sup.11 and R.sup.12 may be bonded to each other to form a ring. A method for producing a polycarbonate resin using the bisphenol composition is also described.
PROCESS FOR THE PREPARATION OF 3,3,4-TRIMETHYLCYCLOHEXYLIDENE BISPHENOL (BP-TMC)
The present inventions relates to the preparation of 3,3,5-trimethylcyclohexylidene bisphenol. Especially, the present invention relates to the preparation of 3,3,5-trimethylcyclohexylidene bisphenol from 3,3,5-trimethylcyclohexanone and phenol in the presence of a gaseous acidic catalyst. The preparation comprises a first drying step and a second drying step wherein in the second drying step the temperature is increased in comparison to first drying step or in the second drying step the pressure is lowered in comparison to first drying step, or in second drying step both the temperature is increased and the pressure is lowered in comparison to the first drying step (d1).

PROCESS FOR REMOVING THC FROM CANNABINOIDS
A method of removing THC and/or THCA from a mixture, the mixture including THC and/or THCA and at least one cannabinoid is provided. The method comprises passing a first feedstock stream through a first chromatographic resin arranged in a simulated moving bed (SMB) chromatography configuration to provide a primary raffinate stream, preparing a second feedstock stream, the second feedstock stream comprising the primary raffinate stream or a concentrated primary raffinate stream, and passing the second feedstock stream through a second chromatographic resin to provide an eluate stream, the eluate stream having less than 0.3 wt % THC on a solvent free basis. The cannabinoid products can be used in various pharmaceutical and nutraceutical applications.
