A process for preparing cyclic esters by means of a transesterification reaction in the gas phase, comprises the steps of: (i) vaporizing a liquid solution of alpha-hydroxy esters, (ii) passing the ester vapors through a reaction zone containing a solid catalyst and (iii) recovering the cyclic esters from the gaseous product stream; and wherein the solid catalyst comprises at least one metal of titanium (Ti) and Zirconium (Zr), and a SiO2 support, and wherein said metal is chemically bound to the SiO2 support through M-O&#x2014;Si chemical bonds.

The disclosure describes a one-step liquid biphasic catalytic process for converting a carbohydrate-containing feedstock, preferably lignocellulose, to light naphtha (e.g., hexane, pentane, methyl cyclopentane, cyclohexane, etc.) in the presence of an acidic reactive aqueous phase and a redox catalyst in the organic extracting/reaction phase. The process provides a cost-effective route for producing light-naphtha components, in presence or not of deoxygenates. The light naphtha components are useful as feedstock for steam and catalytic cracking to produce value-added platform molecules like ethylene and propylene, as precursor for the synthesis of bioaromatics like benzene and as gasoline fuel feedstock, and as fuel additives (e.g., the concomitantly formed oxygenates) to improve the biological origin of carbon in the fuel.

The present disclosure is directed to producing zeolite structures, especially Zeolite SSZ-39, using organic structure directing agents (OSDAs). In particular, the OSDAs comprise isomeric mixtures of N,N-dialkyl piperidinium cations.

The invention relates to a process for preparing a cyclic ester or a cyclic amide, comprising the step of:

Process for preparing cyclic esters and cyclic amides

A process for preparing a cyclic ester or a cyclic amide includes contacting hydroxycarboxylic acid and/or amino-carboxylic acid, an ester thereof, or a salt thereof, with acidic zeolite. The hydroxycarboxylic acid is a 2- or 6-hydroxycarboxylic acid, and the amino carboxylic acid is a 2- or 6-amino-carboxylic acid. The zeolite may include two or three interconnected and non-parallel channel systems, in which a channel system includes 10- or more-membered ring channels, and in which a framework Si/Xratio is at least 24 as measured by NMR. X is Al or B. The zeolite may include three interconnected and non-parallel channel systems, in which at least two channel systems include 10- or more-membered ring channels, and in which a framework Si/Xratio is at least 6 as measured by NMR. The process may be performed at a pressure between 0.5 and 20 bar.
