An electrophotographic photoreceptor which is excellent in sensitivity, durability and environmental capability comprises a photosensitive layer containing dihydroxysilicon phthalocyanine which is monoclinic and has lattice constants a=12.8.+-.1.ANG., b=14.5.+-.1.ANG., c=6.8.+-.1.ANG. and .beta.=94.4.+-.1.degree.. ##STR1##

Dihydroxysilicon compound and electrophotographic photoreceptor

A method for producing an unsaturated glycol diester by reacting molecular oxygen, a carboxylic acid and a conjugated diene in the presence of a solid catalyst containing palladium and tellurium supported on a carrier, wherein an active carbon with the total pore volume of pores having radii of from 18 to 100,000 .ANG. being at least 0.45 cc/g and with the volume of pores having radii of at least 3,000 .ANG. constituting at least 50% of the total pore volume, is used as the carrier for the solid catalyst.

Method for producing an unsaturated glycol diester

A process for producing monosilane, which comprises disproportionating an alkoxysilane of the formula:

Process for producing monosilane

A method for hydrogenating an aldehyde and/or a ketone in the presence of a ruthenium catalyst, wherein said ruthenium catalyst is obtained by reducing an alkali metal ruthenate with a reducing agent selected from the group consisting of methanol, formaldehyde and formic acid.
