Preparation method of 2, 2, 4, 4-tetramethyl-1, 3-cyclobutanediol

The invention discloses a preparation method of 2, 2, 4, 4-tetramethyl-1, 3-cyclobutanediol, which comprises the following steps: dissolving isobutyryl chloride in a first organic solvent, adding triethylamine and zinc powder while stirring, heating to reflux, reacting, cooling, filtering, washing, and carrying out reduced pressure distillation to obtain a distillation substrate; and dissolving the distillation substrate in a second organic solvent, cooling, filtering, introducing hydrogen under the action of a catalyst, and carrying out a reaction to obtain the product. According to the method, on the basis of the process of the BASF company, after triethylamine hydrochloride is formed by triethylamine serving as an acid-binding agent, triethylamine is released from the triethylamine hydrochloride by using proper metal, so that the triethylamine serving as the acid-binding agent can be recycled, and the triethylamine only plays a role of a bridge in a system; through continuous exchange and circulation of a small amount of triethylamine, the reaction is carried out until the reaction is complete.

PROCESS FOR PREPARING 2,2,4,4-TETRAMETHYL-1,3-CYCLOBUTANEDIOL

Disclosed is a method for preparing 2,2,4,4-tetramethyl-1,3-cyclobutanediol, which prepares (E) 2,2,4,4-tetramethyl-1,3-cyclobutanediol (CBDO) which is a final material by sequentially going through (A) methacrylic acid (MAA) as a raw material, and (B) isobutyric acid (IBA), (C) isobutyric anhydride (IBAN), and (D) 2,2,4,4-tetramethyl-1,3-cyclobutanedione (CBDK) as an intermediate.
