    Abstract: The invention relates to a novel solid form of diphenol compound. A process for the preparation of diphenol prills having a spherical shape is disclosed. Said process comprising providing a molten composition comprising from 50 to 100 wt. % of a diphenol compound or a mixture of at least two diphenol compounds, and less than 0.1 wt. % of water; forcing said molten composition through at least one droplet generator means to form droplets; and cooling said droplets to form solid diphenol prills. The diphenol prills obtainable by said process are also one subject-matter of the invention.

    Abstract: Method (M) for the preparation of an end compound from an internal ketone, said method comprising: —synthesizing the internal ketone by a process (P) for the decarboxylative ketonization of a fatty acid, a fatty acid derivative or a mixture thereof in a liquid phase with a metal compound as catalyst in the substantial absence of added solvent, wherein the fatty acid, fatty acid derivative or mixture thereof is added in sequential steps, the first step taking place at a temperature sequentially at a temperature from 100° C. to 270° C., —causing the internal ketone to react in accordance with a single or multiple chemical reaction scheme involving at least one reagent other than the internal ketone, wherein at least one product of the chemical reaction scheme is the end compound that is not further caused to be chemically converted into another compound.
