- METHOD FOR PRODUCING (METH)ACRYLATE
-
A method for producing a (meth) acrylate comprises transesterification reaction of an alcohol and a monofunctional (meth) acrylate with catalysts in combination being cyclic tertiary amines having an azabicyclo structure and compounds containing zinc, separating a solid that contains the catalysts from a reaction product containing a (meth) acrylate, and producing a (meth) acrylate by transesterification reaction of an alcohol and a monofunctional (meth) acrylate, while using the recovered solid catalyst.

- (METH)ACRYLATE MANUFACTURING METHOD
-
The present invention provides a (meth)acrylate manufacturing method characterized in that when manufacturing a (meth) acrylate by an ester exchange reaction between an alcohol and a monofunctional (meth)acrylate using catalyst A and catalyst B together, contact treatment of the ester exchange reaction product with adsorbent C is performed. Catalyst A: One or more kinds of compounds selected from a group consisting of cyclic tertiary amines with an azabicyclo structure and salts or complexes thereof, amidine and salts or complexes thereof, compounds with a pyridine ring and salts or complexes thereof, phosphines and salts or complexes thereof, and compounds with a tertiary diamine structure and salts or complexes thereof. Catalyst B: One or more kinds of compounds selected from a group consisting of compounds comprising zinc. Adsorbent C: One or more kinds of compounds selected from a group consisting of oxides and hydroxides comprising at least one of magnesium, aluminum and silicon.

- MULTIFUNCTIONAL (METH)ACRYLATE MANUFACTURING METHOD
-
[Problem] The purpose of the present invention is to obtain a multifunctional (meth)acrylate with good yield by an ester exchange reaction of a polyhydric alcohol such as pentaerythritol or dipentaerythritol with a monofunctional (meth)acrylate. [Solution] A multifunctional (meth)acrylate manufacturing method characterized in that when manufacturing a multifunctional (meth)acrylate by an ester exchange reaction of a polyhydric alcohol with a monofunctional (meth)acrylate, catalyst (A) and catalyst (B) are used together. Catalyst (A): One or more kinds of compounds selected from a group consisting of cyclic tertiary amines with an azabicyclo structure or salts or complexes thereof, amidines or salts or complexes thereof, and compounds with a pyridine ring or salts or complexes thereof. Catalyst (B): One or more kinds of compounds selected from a group consisting of zinc-containing compounds.

- METHOD FOR PRODUCING ACRYLIC ESTER
-
[PROBLEMS] To provide a method for producing a high boiling acrylic ester having a reduced discoloration without employing distillation in the purification process. [MEANS FOR SOLVING PROBLEMS] A method for producing a high boiling acrylic ester having an APHA of 100 or less, characteristic in that, in the production of a high boiling acrylic ester by the esterification reaction of an acrylic acid and an alcohol, the acrylic acid contains an aldehyde in an amount of 100 ppm by weight or less and the resulting acrylic ester is not distilled in a purification process. The aldehyde is preferably furfural contained in an amount of 45 ppm or less, more preferably, in an amount of 10 ppm or less.
