Methods of Manufacturing
PLACE 95% ETHANOL & MANGANESE DIOXIDE IN REACTION FLASK EQUIPPED WITH DISTILLATION APPARATUS. ADD PYROLIGNEOUS ACID & FINALLY SULFURIC ACID (66 DEG BE) SLOWLY WITH AGITATION, MAINTAINING FINAL TEMP BELOW 40-50 °C. MIXT IS... DISTILLED...ATMOSPHERIC PRESSURE; FRACTION DISTILLING BETWEEN 60-100 °C IS COLLECTED. FINALLY, THE COLLECTED FRACTION UNDERGOES RECTIFICATION. ... AVG YIELD IS 98% BASED ON AMT ETHANOL USED. SOMETIMES DISTILLATE IS FURTHER DIVIDED... AMT OF STARTING MATERIAL...VARY BETWEEN FOLLOWING LIMITS: ETHANOL (95%) KG 12-25; PYROLIGNEOUS ACID (12% ACETIC ACID) KG 10-16; SULFURIC ACID (66 DEG BE) KG 3-8; MANGANESE DIOXIDE KG 2-5.
General Manufacturing Information
...CONSISTS OF @ LEAST 99% WATER, ETHYL ALCOHOL, ETHYL ACETATE, METHANOL, ETHYL FORMATE, ACETONE, ACETALDEHYDE, & FORMALDEHYDE...DISTILLS @ TEMP NOT EXCEEDING 100 °C @ ATMOSPHERIC PRESSURE & LEAVES NO RESIDUE ON EVAPORATION.
...IT SHOULD BE STRESSED THAT RUM ETHERS IN BLENDS WITH FLAVOR INGREDIENTS (IN SUITABLE DOSES) MAY BE DILUTED 200 TO 400 FOLD WITH ALCOHOL OF THE SELECTED STRENGTH. PRODUCTS WITH YIELDS VARYING BETWEEN 1X100 & 1X200 ON DILUTION WITH 70% ALCOHOL ARE SUITABLE FOR DISTILLATE IMITATIONS FOR PASTRY USE.
REPORTED USES: NON-ALCOHOLIC BEVERAGES 67 PPM; ALCOHOLIC BEVERAGES 80-1,600 PPM; ICE CREAM, ICES, ETC 110 PPM; CANDY 320 PPM; BAKED GOODS 230 PPM; GELATINS AND PUDDINGS 1.7 PPM; CHEWING GUM 380 PPM.
CARAMEL IS ADDED TO RUM ETHER FOR COLORING PURPOSES. IN GENERAL, THE ADDITION OF RUM ETHER TO FINISHED LIQUOR DOES NOT EXCEED 2-3% FOR FLAVORING PURPOSES.

Anwendungen
VerwendenRum Ether is a synthetic flavoring agent that is a stable, colorless to yellow liquid of ethereal rum-like note. it should be stored in glass and stainless steel containers. it is used to intensify rum flavors for application in beverages, candy, and ice cream at 67–320 ppm and in alcoholic beverages at 1,600 ppm. it is also termed ethyl oxyhydrate.
Darstellung
synthetischePlace 95% ethanol and manganese dioxide in the reaction flask equipped with distillation apparatus; add pyroligneous acid and finally sulfuric acid (66°Be) slowly with agitation, maintaining the final temperature below 40 to 50°C; the mixture is then distilled under atmospheric pressure and the fraction distilling between 60 and 100°C is collected; finally, the collected fraction undergoes rectification; the rectified fraction exhibits a boiling range between 65 and 98°C; average yield is 98% based on the amount of ethanol used. Sometimes the distillate is further divided into two additional fractions—one more, and one less rich in acetaldehyde; the amount of starting material employed varies between the following limits: ethanol (95%) 12 to 25 kg, pyroligneous acid (12% acetic acid) 10 to 16 kg, sulfuric acid (66°Be) 3 to 8 kg, manganese dioxide 2 to 5 kg.
