P
arr Shaker Type Hydrogenators pro-
vide compact and easily operated sys-
tems for treating chemicals with hydrogen
in the presence of a catalyst at pressures
up to 5 atmospheres (60 psig) and tem-
peratures to 80 °C. They are used primar-
ily for synthesizing or modifying organic
compounds by catalytic hydrogenation,
reduction or condensation, but they are
equally suitable for any other laboratory
procedure in which a liquid and gas must
be mixed vigorously in a glass reactor at
pressures up to 5 atm.
A Long History
The basic design for these hydroge-
nators stems from an apparatus first
described by Voorhees and Adams in 1922
and offered commercially by Parr around
1926. Since that time, Parr has added
many improvements and accessories to
enhance the usefulness of these reactors
to the point where they have become an
essential piece of equipment in almost
all pharmaceutical and organic chemical
laboratories.
Many Applications
The broad usefulness of this apparatus
is best illustrated by the numerous refer-
ences to it in chemical literature published
during the past ninety years. Applications
arise wherever low pressure catalytic
reactions are used, as in the fields of
teaching, research, product development
and in the production of fine organic
chemicals and pharmaceuticals. In addi-
tion, these reactors are frequently used in
quantitative investigations to assay com-
pounds containing hydrogen saturable
double bonds and to test the activity of
catalysts used in industrial processing.
