Sucrose sulfonate esters

Sulfonate Esters. Sucrose sulfonates are valuable intermediates for the synthesis of epoxides and derivatives containing halogens, nitrogen, and sulfur. In addition, the sulfonation reaction has been used to determine the relative reactivity of the hydroxyl groups in sucrose. The general order of reactivity in sucrose toward the esterification reaction is OH-6 OH-6 > OH-1 > HO-2. 

Carbohydrates are hydrolyzed by the action of acids. Since polymer acids are efficient catalysts for the hydrolysis of esters and amides, attempts have been made to use them for the hydrdysis of carbohydrates. Kern and co-workers (36) found that tlw catalytic activity of poly(styrenesulfonic acid) 2 in the hydrolysis of sucrose 25 was comparable to that of sulfuric acid. A sulfonated polystyrene gel (cation exchange resin) was sli tly more effective (37).

Dr. Parker It is very difficult to answer for other processes. Our own work was based on the fact that we wished to obtain a sucrose-derived surfactant which was indeed competitive with linear alkylbenzene sulfonate-types of surfactants. Our product, as produced at the moment, is somewhat cheaper. We also have a range of more highly purified products which are more expensive, but are intended to be competitive with non-ionic surfactants of the sorbitan ester-type. I think processes using solvents ineviteibly must be somewhat more expensive, because of the need to reduce solvent residues to a minimum. We were not able to see how we could do this, but maybe. Monsieur Bobichon, could give his point of view.
