In the present work is studied the synthesis of a nonionic emulsifier and its use for thepreparation of emulsified fuels. The nonionic emulsifier is an ester and it was prepared in twoways: the addition of chemical compounds containing active hydrogen (esters obtained out offatty acids and sorbitol) to an oxyran (ethylene-oxide); the transesterification of the ethoxylatedsorbitol with the methylic ester of a fatty acid (oleic acid). The products obtained were furtherpurified through a patented procedure, to obtain stabilized compounds. The ester of oleic acidwith sorbitol was obtained by the transesterification of the sorbitol with methyl oleat. Theproduct content of oxiethylenic groups was 20-40 relative to a sorbitol molecule. Thesynthesized emulsifiers were tested for the preparation of emulsifiedoil-in-water fuels used for burning processes improvement and implicitly reductions ofpollutants. |
