Homogeneous Reforming of Aqueous Ethylene Glycol to Glycolic Acid and Pure Hydrogen Catalyzed by Pincer-Ruthenium Complexes Capable of Metal–Ligand Cooperation

Glycolic acid is a useful and important α-hydroxy acid that has broad applications. Herein, the homogeneous ruthenium catalyzed reforming of aqueous ethylene glycol to generate glycolic acid as well as pure hydrogen gas, without concomitant CO2 emission, is reported. This approach provides a clean and sustainable direction to glycolic acid and hydrogen, based on inexpensive, readily available, and renewable ethylene glycol using 0.5 mol % of catalyst. In-depth mechanistic experimental and computational studies highlight key aspects of the PNNH-ligand framework involved in this transformation.

Preparation method for 2,4-dichlorophenoxyacetic acid

The invention provides a preparation method for 2,4-dichlorophenoxyacetic acid. The preparation method comprises the following steps: A) reacting a divalent salt of glycolic acid as shown in a formula(I) with 1,2,4-trichlorobenzene under the action of a catalyst so as to produce 2,4-dichlorophenoxyacetate as shown in a formula (II); and B) acidizing 2,4-dichlorophenoxyacetate so as to obtain 2,4-dichlorophenoxyacetic acid. According to the invention, 1,2,4-trichlorobenzene is creatively used for replacing phenol and chlorophenol and subjected to a condensation reaction with glycolate so as toproduce 2,4-dichlorophenoxyacetate, and hydrolysis is carried out so as to prepare 2,4-dichlorophenoxyacetic acid; so such a technical scheme effectively avoids the usage of phenol or chlorophenol, overcomes the problems of peculiar smell of an operation place and production of waste gas, waste water and industrial residues, greatly improves the operation environment of the operation place and produces good environmental protection benefits, and the reaction has high yield and purity.

Hydrolysis kinetics of chloroacetic acid with sodium hydroxide under strong alkaline conditions

The hydrolysis of chloroacetic acid and sodium hydroxide is carried out at 45-85 °C by using equal mole of sodium chloroacetate and alkali. Using reasonable approximation, the hydrolysis reaction is proved to be a second-order reaction when the conversion is less than 95 % and the kinetic rate coefficients are determined. The activate energy is calculated 103 kJ mol-1.
