Reaktionsschritte

An aqueous solution of sodium sulfite and bisulfite was prepared by mixing 38.8 lbs of sodium metabisulfite and 17.0 lbs of sodium sulfite with 88.2 lbs of water. The salt solution was metered into the recycle loop at a rate of 7.6 lbs per hour. Simultaneously a glyceryl epoxide wherein R is normal alkyl of 12 to 15 carbon atoms, R' is hydrogen and n is average value of 1 according to Formula 1 was metered into the recycle loop at a rate of 10.0 lbs/hour. The recycle loops residence time was thirty minutes. At steady state, the temperature maintained in the recycle loop was 160° C. and the pressure was 100 psig. The residence times were varied in sequential runs by increasing the metering rates of the reactants proportionately to achieve residence times of 15, 10 and 5 minutes.
