Pulping Liquors and Uses Thereof

The present invention relates generally to the generation of bio-products from organic matter feedstocks. More specifically, the present invention relates to the use of pulping liquors in the hydrothermal/thermochemical conversion of lignocellulosic and/or fossilised organic feedstocks into biofuels (e.g. bio-oils) and/or chemical products (e.g. platform chemicals).

Method for producing 3,5-dihydroxy-4-methoxybenzyl alcohol from plankton

[Problem] The purpose of the present invention is to provide a method for collecting seawater that contains plankton and generating DHMBA (dba), which is an antioxidant, from the plankton contained in the seawater. [Solution] The present invention is characterized in that: collected seawater containing plankton is filtered using a filter, the cell contents are removed from the plankton remaining on the filter, the removed cell contents are subsequently heated, and 3,5-dihydroxy-4-methoxybenzyl alcohol is produced from the heated product; and the plankton are assumed to be diatoms.

Process to produce a mono vinyl ether
11401227 · 2022-08-02 · ·

A process produces a mono vinyl ether, R—O—CH═CH.sub.2. R represents an organic group with at least three carbon atoms. The process involves reacting a mono hydroxy compound. R—OH, with acetylene in presence of a catalyst to get a product mixture containing the mono vinyl ether, unconverted mono hydroxy compound, and the catalyst. To the product mixture, an ester is added that contains at least one ester group, X—O.sub.2C—. X is a hydrocarbon group containing less carbon atoms than R. The remaining mono hydroxy compound R—OH is reacted with the ester in the presence of the catalyst to get a transesterification product containing at least one ester group, R—O.sub.2C—, and an alcohol, X—OH. The mono vinyl ether is isolated from the product mixture obtained after the ester addition, optionally followed by purification of the mono vinyl ether by distillation.
