The Key Role of Water in Solid-Liquid Phase Transfer-catalysed Substitution Reactions

Traces of water are shown to be essential for substitution reactions catalysed by quaternary ammonium salts; in chloride-formate exchange maximum rate is observed with 0.2percent water content of the formate salt, and addition of dehydrating agents reduces the maximum rate by 50percent.

Method for preparing formate-type compound

The invention discloses a method for preparing a formate-type compound. The method comprises the following steps of: adopting an alcohol-type compound and 1,3-dihydroxyacetone as reaction raw materials, and under the existence of a composite catalyst and an oxidant, reacting for 2-48 hours in a reaction medium in a reactor at a reaction temperature of 25-100 DEG C so as to obtain the formate-typecompound. The method disclosed by the invention is simple, and is mild in reaction condition, and by the method, a target product can be obtained by low cost and high yield; the used catalyst has highcatalytic activity, and is easily separated from a reaction system to be repeatedly used; the whole process is environment-friendly, and the reaction raw material (1,3-dihydroxyacetone) is easily converted from a side product (glycerol) of biodiesel, so that the utilization of the glycerol is promoted.

Compounds, Compositions and methods for insect control

Rapidly acting compositions having vapor phase insecticidal activity comprise natural products or natural product-based materials. Further, these materials are non-petroleum based, are typically 100% biodegradable, and typically do not persist in the environment, unlike traditional pesticides. The compositions kill susceptible insects on contact in seconds, even the notoriously hardy peripleneta species. The compositions also kill insects behind cracks and crevices and when sprayed onto absorbent surfaces such as wood and plasterboard, where traditional contact insecticides work poorly or not at all. New methods of testing insecticides can be used to quantify these effects.

Esterification of 1,4-dichlorobutane with sodium formate under solid-liquid phase transfer catalysis. A kinetic study.

Kinetic data are reported regarding the esterification of 1,4-dichlorobutane with sodium formate catalyzed by quaternary ammonium salts as a model for reactions in series, under solid-liquid phase transfer conditions.The process was found to follow a consecutive first-order mechanism of the general type A --> R --> S.The reactivity of the quaternary ammonium salts with regard to the counteranion was Cl(1-) > Br(1-) > I(1-) > HSO4(1-).The reaction rate was linearly dependent on catalyst concentration up to 12 molpercent of catalyst relative to the substrate.Above this concentration the rate was constant and independent of the amount of the catalyst.The activation energy of the two consecutive steps was found to be similar (21 kcal/mol).Therefore, the product distribution (R/S) is not appreciable affected by temperature.A mechanism termed "Thin aqueous boundary layer" is suggested for nucleophilic displacement reactions under solid-liquid phase transfer conditions.Key words: phase transfer catalysis, series reactions, kinetic study.

One-Pot Conversion of Primary Alkyl Chlorides and Dichlorides into Alcohols, Diols, and Ethers via Formic Ester Intermediates under Phase-Transfer Conditions

A procedure for the synthesis of alkyl formates, 1,ω-alkanediyl diformates, and unsaturated analogs from alkyl (or 2-alkenyl) halides and sodium formate under solid/liquid phase-transfer conditions is reported.For conversion into alcohols or diols, respectively, the formic esters can be directly hydrolyzed in the reaction mixture of their preparation.Using a related procedure, cyclic ethers are prepared from 1,ω-dichloroalkanes, sodium formate, and potassium hydroxide under solid/liquid phase-transfer conditions.
