Title: Process of chlorination of aromatic hydrocarbons
IPC: C07C17/12
Filed: 1946-01-03
Abstract: Aromatic hydrocarbons are treated with chlorine in the presence of chlorination catalysts in a bath which contains in addition to the hydrocarbon at least two of its chlorinated derivatives. Solid hydrocarbons may be treated either when fused or in a solvent and pressure may be necessary.  The process is carried out in an apparatus consisting of two limbs connected top and bottom and made continuous by the regulation of the supply of reactants to the first limb together with the withdrawal of liquid from the bottom of the second limb so that the bath is maintained at a constant predetermined composition, circulation being effected by passing the reactants into the bottom of the first limb and removing liberated hydrochloric acid from the top of the second. The withdrawn liquid is separated from insufficiently chlorinated liquor which is returned to the chlorinator together with fresh hydrocarbon.  For higher degrees of chlorination, the process is worked in successive stages and at higher temperatures, thus the above-separated liquid may be treated to yield the chlorinated products or, either before or after such treatment, passed on to a second similar chlorinator for a more thorough chlorination at a temperature higher than that of the boiling point of the original hydrocarbon although lower than but near to that of the least chlorinated hydrocarbon present. Chlorinated derivatives are removed from the hydrochloric acid vapours liberated in the second chlorinator by counter-current washing with the liquor sent from the first.  In examples (1) and (2), benzene is chlorinated using iron filings as catalyst in baths composed of benzene, monochlorobenzene and dichlorobenzenes, the products being monochlorobenzene and dichlorobenzenes, and (3) naphthalene, mixed with a return of chloronaphthalenes and dissolved in carbon tetrachloride, is chlorinated using ferric chloride as catalyst in a bath composed of naphthalene, chloronaphthalenes and carbon tetrachloride, the products being tetra- and pentachloronaphthalenes.  A two-stage process is also described in which in the first stage benzene is converted to monochlorobenzene and dichlorobenzenes which are isolated and a mother liquor rich in dichlorobenzenes which is further chlorinated in a second chlorinator.

Abstract: PROBLEM TO BE SOLVED: To prevent the gap corrosion of an orifice and prevent leakage of sea water by providing structure supplying oxygen to an orifice surface between a packing and the orifice or between lining and the orifice to connect a part between flanges. SOLUTION: The connection part of flanges 4, once disassembled for the confirmation of the existence of the corrosion of an orifice, is reconstituted. In this case, since lining 3 is executed on a sea water system piping inner face and also executed on the connection face of the flange 4, the corrosion of the flange 4 due to sea water 5 of inner fluid need not be considered. A sethengh a place oxygen-supplied to the surface of a stainless steel-made orifice is superior in corrosion resistance, corrosion resistance is often damaged, because oxygen supply is insufficient in a gap part of a contact face or the like with a packing.  An oxidizing agent blending packing 1 for blending an oxidizing agent to the packing between the stainless steel-made orifice 2 and lining 3 is set to enable oxygen supply, and after setting, the connection part of the flanges 4 is fixed watertightly with double cut screws 7 and a tightening bolt 6.
