The catalsyt is preferably used in the form supported on a carrier in an amount of 2W15wt% supported thereon and prepared as follows: for example, a carrier is dipped in an aqueous solution of silver nitrate and copper nitrate, calcined at 200W500°C in air and hydrogenated at 200W400°C just before the use in the reaction.

PROCEDURE FOR THE PREPARATION OF A CINNIC ACID ESTER BY THE CONVERSION OF A STYRENE COMPOUND, CARBON MONOXIDE, AN ALCOHOL AND OXYGEN USING A CATALYST

Preparation of cinnamate esters

Disclosed herein is a process for preparing a corresponding cinnamate ester by reacting a styrene compound, carbon monoxide, an alcohol and oxygen by the use of (l) metallic palladium or a compound thereof, (2) a copper compound, (3) a compound of at least one metal selected from Groups 4A, 5A, 7A, 8A (the iron group only) and 2B in the Periodic Table and (4) a halogen compound as a catalyst which comprises treating the catalyst components recovered from the reaction liquid after completion of the reaction with an oxidizing agent in the presence of an organic acid to regenerate their catalytic activity, using the resulting catalyst components again in the reaction as a catalyst and repeating the foregoing procedure. The regenerated catalyst is recovered in catalytic activity to the extent of that of a fresh catalyst and thus gives a high reaction performance in the subsequent reaction. Thus, the catalyst contain­ing expensive metal can be used circulatively.

Preparation process of cinnamate esters

A cinnamate ester is prepared by reacting carbon monoxide, oxygen, and its corresponding styrene compound and alcohol in the presence of a catalyst which contains, as essential components, (a) a platinum group metal or a compound thereof; (b) a copper or iron compound; and (c) a compound of at least one metal selected from Groups 4A, 5A, 7A, 8A(the iron group only), 1B(exclusive of copper) and 2B.

仏壇

【課題】簡易な構造で印象的な照明効果を有する仏壇を提供する 【解決手段】本発明に係る仏壇８０は、照明部５０の発光手段５２が点灯すると、背景画像４７が背板部４０の表面紙４４に映し出される。このとき、背景画像４７は半透明の透光性シート４６及び表面紙４４を通して映し出されるため、適度にぼやけ霞がかった幻想的な画像として表面紙４４に浮かび上がる。また、照明部５０からの光を反射板４８で反射して間接的に照射することで、全体的な照度が低下するとともに平均化され背景画像４７はむらなく適度な照度で映し出される。これにより、本発明に係る仏壇８０は仏壇のイメージを損なわない厳かな印象の照明効果をユーザに与えることができる。 【選択図】図１
