Abstract
A method producing a surfactant from glycerol by converting glycerol, in a first step, to glycidol, polymerizing glycidol to an aliphatic alcohol and finally substituting a hydroxyl group with a substitute anion.
Claims21
A method of producing a surfactant from glycerol which includes the steps of:
- (a) converting glycerol to glycidol,
- (b) polymerizing glycidol to produce an aliphatic alcohol with molecular formula CnH(2n)O, wherein n is a numerical integer in the range 5 to 25;
- and
- (c) substituting the hydroxyl moiety of the alcohol with a suitable head group.

A method of producing an explosive compound from glycerol which includes the steps of:
- (a) converting glycerol to glycidol;
- (b) polymerizing glycidol (the monomer) to produce an aliphatic polyol the polymer) with molecular formula CxH(2X+2)OY, wherein X and Y are numerical integers in the range 3 to 30 and 3 to 15 respectively;
- (c) activating the aliphatic polyol by substituting each of the hydroxyl moieties with a suitable leaving group to form an activated intermediate;
- and (d) nitrating the activated intermediate to substitute each of the leaving groups with a nitrate moiety to produce the explosive compound.
