Claims (18)
1. A continuous process for preparing benzyl alcohol which comprises continuously charging benzyl chloride and an aqueous solution of an alkaline component selected from the group consisting of alkali metal and alkaline earth metal hydroxides or carbonates to a hydrolysis zone at a rate adjusted to provide turbulent flow thereSn, effecting the hydrolysis of tbe benzyl chloride to form benzyl alcohol at elevated temperature and pressure within the hydrolysis zone, continuously withdrawing the effluent from the hydrolysis zone and thereafter recovering the benzyl alcohol contained therein.
2. The process of Claim 1, wherein the aqueous alkaline solution contains water and from 2 to 20 weight percent of the alkaline component claimed in Claim 1 *
3. The process of Claim 2, wherein the alkaline component is present in the aqueous alkaline solution in an amount of from about 5 to about 15 weight percent.
4. The process of Claim 2, wherein the alkaline component contained within the aqueous alkaline solution is charged in an amount ranging from about 1 to about 75 mol percent above the amount stoichiometrically required to hydrolyze each mol of benzyl chloride.
5. The process of Claim 2, wherein the aqueous alkaline solution contains from about 5 to about 1 weight percent of the alkaline component and the alkaline component is charged in an amount ranging from about 5 to about 15 raol percent above the amount stoichiometrically required to hydrolyze each mol of benzyl chloride.
6. The process of Claim 2 wherein the alkaline component is sodium carbonate.
7. The process of Claim 2 wherein the alkaline component is sodium hydroxide.
8. The process of Claim 1 wherein the benzyl chloride charged to the hydrolysis zone is admixed with an inert solvent.
9. The process of Claim 8 wherein the solvent is toluene .
10. The process of Claim 1 wherein the hydrolysis is o o effected at a temperature of from about 150 to about 550 C and at a pressure sufficient to maintain the reactants in liquid phase .
11. The process of Claim 10 wherein the temperature o o range is from about l8o to about 275 C.
12. The process of Claim 1 wherein the benzyl chloride and the aqueous alkaline solution are charged in admixture to the hydrolysis zone at a rate adjusted to provide a turbulent flow rate therein having a Reynolds number above about 2,100.
13. The process of Claim 12 wherein the Reynolds number is above about 4000.
14. 1 . The process of Claim 1 wherein the benzyl chloride is charged in admixture with an aqueous alkaline solution containing water and from about 2 to about 20 weight percent of sodium carbonate with the amount of the sodium carbonate being adjusted to a range of from about 1 to about 75 mol percent above the amount stoichiometrically required to hydrolyze each mol of benzyl chloride, the admixture of benzyl chloride and the aqueous alkaline solution is charged to the hydrolysis zone at a rate adjusted to provide a flow rate therein having a Reynolds number above about kOOO, and the hydrolysis of the benzyl chloride to benzyl alcohol is effected within the hydrolysis zone at a o o temperature of from about 150 to about 350 C and at a pressure sufficient to maintain the reactants in liquid phase.
15. The process of Claim 14 wherein the benzyl chloride is charged in admixture with an aromatic hydrocarbon solvent.
16. The process of Claim 15 wherein the solvent is toluene which is admixed with the benzyl chloride in equal weight parts.
17. The process of Claim l wherein the temperature is o o from about 180 to about 275 C.
18. The process of Claim Ik wherein the sodium carbonate is present in the aqueous alkaline solution in an amount of from about 5 to about 15 weight percent and the amount of sodium carbonate is adjusted to a range of from about 5 to about 15 mol percent above the amount stoichiometrically required to hydrolyze each mol of benzyl chloride · Tel-Aviv, January 10th, 1971
