UNITED STATES PATENT OFFICE.
RUDOLF SCHMITT, OF DRESDEN, ASSIGNOR TO DR. F. VON ITEYDEN NAUTI- FOLGER, OF RADEBEUL, SAXONY, GERMANY.
PROCESS OF MAKING BETA-NAPHTHOL CARBON ACID.
SPECIFICATION forming part of Letters Patent No. 410,295, dated September 3, 1889.
Application filed June 22, 1889. Serial No. 315,232. (No specimens.)
To all whom, it may concern.-
Be it known that I, RUnoLr ScHMrr'r, of Dresden, in the iliinu'doin oi Sa." my, German Empire, have invested a new and Im- 5 proved Process of lilanulacturin l-leta-Naphthol Carbon Acid, of which the following is a specification.
The invention consists in a process for the manufacture of beta-naphthol carbon acid of: re the melting-point of 216" Celsius by meansol the reaction of carbonic acid upon the alkaline salts of the beta-na iihthol under pressure and at a temperature of 200 to 250 ("elsius.
The beta-naphthol carbon acid, the prod'uc 15 tion of which has been specified in United States Patent No. 350,468, granted to myself: and Carl Kolbe jointly, on the 5th day of January, 1880, is produced, if carbonic acid is allowed to react on the alkaline salts of 20 the bcta-naphthol under pressure and at a temperature of 120 to H5 Celsius. The
very inconstant acid thus obtained again decomposes very easily into carbonic acid and beta-naphthol and melts at 157 Celsius.
z 5 I have now found that if in the above op- Celsius, consisting in producing the reaction of carbonic acid upon the alkaline salts of 40 the beta-naphthol under pressure and at a temperature of 200 to 250 Celsius, substantially as herein set forth.
In testimony that 1 claim the foregoing, as my invention I have signed my name in pres- 5 ence of two subscribing witnesses.
RUDOLF SCHMIIT.
