权利要求

1. A PROCESS FOR THE PRODUCTION OF INDANOL-(4) OR INDANOL(5), SAID PROCESS COMPRISNG ADDING AN ALKALI METAL SALT, ALKALINE EARTH METAL SALT OR AMMONIUIM SALT OF INDAN-4- OR INDAN-5SULFONIC ACID TO POTASSIUM HYDROXIDE AND AT LEAST ONE ALKALI METAL SALT OF A SECOND ACID SELECTED FROM THE GROUP CONSISTNG OF C1-C6 ALIPHATIC MONOCARBOXYLIC ACIDS C1-C16 ALIPHATIC POLYCARBOXYLIC ACIDS, HYDROXY-SUBSTITUTED C1-C16 ALIPHATIC MONOCARBOXYLIC OR POLYCARBOXYLIC ACID AND ALKOXY SUBSTITUTED C1-C6 ALIPHATIC MONOCARBOXYLIC OR POLYCARBOXYLIC ACIDS, SAID ALKOXY GROUP HAVING 1-4 CARBON ATOMS, WHILE HEATING AND AGITATING THE RESULTING MIXTURE AT A TEMPERATURE OF ABOUT 250*-300*C TO FORM A MELT, STIRRING SAID MELT FOR ANOTHER FOUR HOURS AFTER ALL SAID SULFONATE HAS BEEN ADDED, AND RECOVERING SAID INDANOL-(4) OR INDANOL-(5) FROM SAID MELT, WHEREIN SAID SULFONIC ACID SALT, SAID POTASSIUM HYDROXIDE AND SAID SALT OF SAID ACID ARE IN A MOLAR RATIO OF ABOUT 1:3-25:0.1-2.

2. Process of claim 1 in which said temperature is about 270*-290*C.

3. Process of claim 1 in which said molar ratios are about 1:6-10:0.5-1.

4. Process of claim 1 in which the sulfonate contains as a cation sodium, potassium or an ammonium radical.

5. Process of claim 1 in which the second acid is acetic acid, propionic acid, butyric acid, isobutyric acid, glycolic acid, methoxyacetic acid, malic acid, tartaric acid or citric acid.

6. Process of claim 3 in which the salt of the second acid is a sodium or potassium salt of acetic acid.

7. Process of claim 3 in which said temperature is about 270*-290*C.

8. Process of claim 1 in which the salt of said second acid is sodium acetate or potassium acetate, and the salt of the sulfonic acid is a potassium, sodium or ammonium sulfonate.

9. Process Of claim 7 in which the salt of said second acid is sodium acetate or potassium acetate, and the salt of the sulfonic acid is a potassium, sodium or ammonium sulfonate.
