| titleOfInvention | Process for the manufacture of n-monoalkyl-p-aminophenol |
| abstract | 274,175. Potts, H. E., (Chemische Fabrik Gr³nau Landshoff & Meyer Akt.-Ges.). April 10, 1926. N-monoalkyl - p - aminophenols are made by hydrolysing O-alkyl-N-alkyl-acidyl-p-aminophenols with sulphuric acid, under conditions of temperature, time, strength and amount of acid which exclude the formation of sulphonated derivatives. In examples of the limiting conditions, methylphenacetin is heated with 6 equivalents of 50 per cent sulphuric acid for 3 hours at 139‹ C., and with 3 equivalents of 70 per cent acid for 4¢ hours at 146‹ C. A table showing how the various factors may be varied within these limits is given. |
