Abstract: Disclosed is a shaped zeolite catalyst used for liquid phase organic reactions. The shaped zeolite catalyst is composed of substantially spherical particles having a particle diameter substantially in the range of from 70 to 300 .mu.m, and which has fine pores having a pore volume of 0.4 to 1 cc per gram of the shaped catalyst and a median pore diameter based on the pore volume of 1,000 to 5,500 .ANG..

Abstract: A para-substituted halogenobenzene derivative is prepared by halogenating a benzene derivative in the liquid phase in the presence of a molded zeolite catalyst body comprising, based on the weight of the molded zeolite catalyst body, 10 to 95% by weight of an L-type zeolite as the anhydrous state and 5 to 90% by weight of amorphous silica.

Abstract: A p-substituted halobenzene derivative, which is very valuable in industry, can be obtained by halogenation of benzene and/or a benzene derivative in the liquid phase using, as a catalyst, a faujasite type zeolite in the presence of any one member selected from the group consisting of sulfur-containing compounds, nitrogen-containing organic basic compounds, salts of said nitrogen-containing organic basic compounds, and a mixture of said nitrogen-containing organic basic compounds and salts thereof.

Abstract: p-Substituted halogenated benzene derivatives are prepared at a high selectivity by halogenating benzene and/or benzene derivatives by using as a catalyst a zeolite modified with a metal salt.

Abstract: In the liquid phase chlorination of benzene derivatives including benzene per se in the presence of a zeolite possessing the main pores having the opening formed of a 12-membered oxygen ring; para-substituted chlorinated benzene derivatives are preferentially obtained by adding a small quantity of a quaternary ammonium salt or salts to the reaction mixture.

Abstract: Olefins are hydrated to the corresponding alcohols in the presence of at least one crystalline alumino-silicate selected from offretite, ferrierite and erionite. The offretite, ferrierite and erionite are preferably characterized by X-ray diffraction patterns shown in Tables 1 and 7; Tables 2, 8 and 9; and Table 3, respectively. At least a part of the exchangeable cations in the offretite, ferrierite and erionite may be exchanged with at least one cation selected from a hydrogen ion, an alkaline earth metal ion and a rare earth metal ion. Furthermore, at least a part of the exchangeable cations in the erionite may be exchanged with an ammonium ion and/or an alkali metal ion.

Abstract: Conjugated dienes containing a cyano group having the formula ##EQU1## wherein R.sub.1 and R.sub.2 represent hydrogen atom, an alkyl group or a phenyl group are produced by dehydrating 2-cyano-3-hydroxy-1-olefins in the presence of an alkaline catalyst while continually removing the product being formed from the reaction system.
