摘要： The present specification provides a method of preparing a heterogeneous linear carbonate, including transesterifying an aliphatic alcohol and a symmetric linear carbonate in the presence of a catalyst, wherein the catalyst is a porous type basic ion exchange resin having an exchange capacity of 1 (eq/l-wet resin) or more and 1.5 (eq/l-wet resin) or less. The preparation method of the present specification provides a method of preparing a heterogeneous, symmetric linear carbonate and asymmetric linear carbonate in high yield without a process of reactive distillation.

摘要： The invention relates to a method of manufacture of a thermoset polymer foam that is at least from 50 to 100 percent by weight of renewable raw material resources and to the foam obtained by the method. Foam is obtained from a two-component system that cures at room temperature after mixing in the presence of a strong base catalyst by carbon-Michael addition polymerization, forming mechanically rigid and highly cross-linked polymer. Both components of the carbon-Michael addition are developed from bio-based feedstock.

摘要： [Object] Provided are a 11 C-labeled acyclic retinoid that can be synthesized in a short time with a high yield and can be suitably used for PET for elucidating intracerebral kinetics, a PET probe using it, and methods for producing them.
[Solution] The 11 C-labeled acyclic retinoid of the present invention is characterized by being represented by the following chemical formula (a). This compound can be produced by a coupling step of cross-coupling a methyl iodide labelled with 11 C and the following organotin compound (b) (provided that in the formula, R 1 and R 2 represent alkyl groups which may have a branch) in an aprotic solvent in the presence of a palladium complex, a phosphine ligand, and a cuprous halide.-
