Sulphuric acid 600Be’ (148 kg) is run into
cold water (1390 kg) in an enameled iron vessel, and m-chloroaniline (100 kg) is added in a thin steam, with agitation,
during 11/2 hours. The mixture is stirring for 3 hours
and cooled to below 00C by
circulation of brine. Diazotisation is
carried out by addition of a solution of sodium
nitrite (56.8 kg, ii.e. 5% excess) in water (130 l) during about 1/2 hour, keeping the
temperature between 00C and 100C. The usual tests are
carried out to ensure the presence of excess acid and a final excess of nitrous
acid, which should persist for 1/2 hour. The final
temperature should be 100C.
Active carbon (1.3 kg) is added, and after 1/2 hour’s
stirring the solution is filtered. Pure
borax (45 kg) is added to the filtrate and stirring is continued for 1/2 hour. The temperature is then reduced to 00C and hydrofluoric
acid (37.7 kg at 100%) is added as a solution of about 70%. The temperature
rises and again reduced to 00C. Further charges of borax (45 kg) and hydrofluoric acid (37.6 kg at 100%) are then added. The
hydrofluoric acid is drawn in under pressure from an iron container using a
lead inlet pipe passing below the surface of the liquid. Agitation is continued
at 00C for 6 hours and the precipitated diazonium salt is then filtered off and centrifuged. Yield of paste 167 kg at 51.8% (molec. Mass
127.5), i. e.86.5% of the theoretical. The product is mixed with anhydrous zinc
sulphate (87 kg) and dried at 40-450C. It is standardized to a
content of zinc sulphate monohydrate of 1.50 parts per part of 100% diazonium
salt (molec. Mass 127.5) and a strength of 15.1% (molec. Mass 127.5), the final
diluents being disodium naphthalene-1,6-disulphonate, which also serves as solubilising agent.
