Solvent... Versatile Intermediate... Heat Transfer Fluid All These in HOOKER MONOCHLOROBENZENE Hooker Monochlorobenzene is serving chemists in many different ways: 1.

HOOKER RESEARCH PRESENTS 3-NITRO-4-CHLOROBENZOTRIFLUORIDE C6H3CF 3 [3-N02,4-CI]

As a good general solvent, it is especially helpful in the manufacture of paints, varnishes, lacquers and their removers.

2.

As* an insecticidal intermediate, it is used in the preparation of D D T and other insecticides.

3.

As a dyestuff intermediate, it is used in the preparation of sulfur black and brown dyes.

4.

As a chemical intermediate, it is used in the manufacture of many organic synthetics, such as picric acid, phenol, dinitrochlorobenzene, drugs and perfumes.

5.

As a heat transfer fluid—for condensing vapor systems where glass enameled jackets cannot stand high steam pressure, monochlorobenzene can be used in the range from its boiling point (130°C) u p to about 190°C.

Hooker now adds S-Nitro-4-chlorobenzotrifluoride. It is a thin yellow oily liquid. Indications are that 3-Nitro-4-chlorobenzotrifluoride is a valuable addition to the group of chemical intermediates. It is subject to further ring substitution in the n u m b e r 5 position. T h e nitro group may be reduced in alkaline media. T h e chlorine atom is very stable and unlike other benzotrifluoride compounds, hydrolysis results in attack on the C F 3 group. Patent literature discloses a variety of applications for nitrochlorobenzotrifluoride in the preparation of azo dyestuffs and pharmaceuticals. At present available in pilot plant quantities, production in commercial quantities can be quickly undertaken when circumstances warrant.
