Paragraph 0019, (2017/04/28)
The invention discloses a new synthetic method of allyl acrylate. According to the method, an organic silicon monomer with functional groups is used, and the allyl acrylate is prepared under the soft reaction condition. The synthetic method of the allyl acrylate includes three steps that (1) acryloxytrimethylsilane is synthesized; (2) allyloxy silane is synthesized; and (3) the acryloxytrimethylsilane and the allyloxy silane are mixed. According to the raw materials used in a reaction, chlorine elements are fully converted into inorganic salt, low-boiling-point chloride like phosphorus trichloride is not used, and it is guaranteed that the chlorine elements are not contained in a prepared product; reaction conditions are soft, and the requirement for the equipment is not high; purification is easy, boiling points of all components are large in difference, and reduced pressure distillation separation is easy; water washing is not needed, and amplification is easy; and trifluoromethanesulfonic acid serves as a catalyst, the high acidity is achieved, and double bonds cannot be damaged.

A series of unsaturated esters were prepared via condensation of sodium carboxylates and alkenyl halide under the condition of macroporous polystyrene grafted quarternary ammonium salt as recyclable phase transfer catalyst, NaI as co-catalyst, Cu powder as inhibitor and H2O as solvent. Under optimal conditions, products yields are 78.2~ 96.0%. The catalyst can be convenient recycled and reutilized for about five times without losing its activity obviously.

The ability of diverse commercial lipases and whole cells (fungal resting cells) to synthesise allyl and dichloropropyl acrylate from allyl dodecanoate through an interesterification process is presented. The process was carried out without solvent in a conventional batch system. The best biocatalyst among those studied was the commercial enzyme CALB (Candida antarctica lipase B immobilised onto a macroporous acrylic resin). The reaction was sensitive to water activity, and a decrease in the yield was observed at the highest activity studied. CALB could also be applied to diverse acrylic derivatives, although the yields decreased using either ethyl methacrylate or acrylic acid.

supporting information; experimental part, p. 4696 - 4699 (2009/12/08)
An unprecedented coupling of a P - C and a C - C bond-forming event In a practical operation was developed to access medicinally relevant phosphinic structures. The strategy relies on an Ireland-Claisen rearrangement triggered by the phospha-Michael addition of silyl phosphonltes to allyl acrylates. This protocol was extended to a more versatile three-component variant that utilizes phosphinic acids, acryloyl chlorides, and allylic alcohols as starting materials.

Page/Page column 16, (2008/12/07)
A process for preparing acrylic acid, in which an acrylic acid-comprising product gas mixture obtained by catalytic gas phase partial oxidation of a C3 precursor of acrylic acid is fractionally condensed in a condensation column provided with internals ascending into itself with side draw removal of crude acrylic acid and with liquid phase draw removal of acrylic acid-comprising acid water, and acrylic acid present in acid water is taken up into an extractant and then removed from the extractant and recycled into the condensation column, or taken up in aqueous metal hydroxide, or sent to further purification of the crude acrylic acid.

The invention concerns the production of acrylic acid from propane in the presence of molecular oxygen. Said method consists in passing a gas mixture comprising propane, molecular oxygen, water vapour and, optionally, an inert gas, on a catalyst of formula (I) Mo1VaTebNbcSidOx to oxidize propane into acrylic acid, the propane/molecular oxygen mol ratio in the initial gas mixture being not less than 0.5.
