Abstract This thesis comprises a general introduction which gives a short account on the epoxidation of mangifera oil, which are used 1 n many purposes such as plasticizers and stabilizers. -he In sitg reagents are preferable for the epoxidation of isolated double bonds and thus achieved commercial importance.(138) The review of literature is a bibliographic survey of mangifera fatty acids composition, separation of saturated fatty acid/unsaturated fatty acids , preparation of 2- alkenolc. aCl.ds, fatty alcohols and hydrocarbons. And also, naturally occurring epoxy fatty acids and their epoxy glycerides, epoxidation of vegetable oils and fatty acid derivatives by in situ techni que using sulphuric acid and cation exchange resins as catalyst. The experimental part includes, oil extraction, chemical characteristics (Acid value, iodine value, saponification value and unsaponiable matter), separation of fatty acids, preparation of trans 2 - octa decenOlC. aCl.d , preparatlo.n 0f esters for cis g-octadecenoic and trans 2-octadecenoic acids. Reduction of fatty methyl esters to the corresponding fatty alcohols then to the hydrocarbons was undertaken. - Epoxidation of crude Mangifera oil and free fatty acids. - Epoxidation of fatty esters for cis 9-octadecenoate and trans 2-octadecenoate. - Epoxidation of fatty alcohol and acetylated derivatives. - Epoxidation of hydrocarbons. - preparation of fatty 2-morpholinones and 2-oxazolidones. The results of all above studies are illustrated by 13 tables and 13 figure which revieled the following. cis 9-octadecenol and trans 2-octadecenol were prepared in about 75-79%. cis 9-octadecene and trans 2-octadecene were prepared in about 77-78%. - The yield of epoxidized crude mangifera oil was 20.4%, (using 2% conc H2S0 4 as catalyst) and free cis 9-octadecenoic, trans- 2-octadecenoic were 8.65 and 8.35 respectively. - Epoxidation of fatty esters (methyl, butyl, n-hexyl and cyclohexyl) at the same conditions gave 78.439% for n-hexyl ester of cis 9-octadecenoate decrease in case of trans- 2-octadecenoate to about 65.71% yield. - The yields of epoxidized fatty alcohols at the same conditions were 16.34%, 11.80 for cis 9-octadecenol and trans- 2-octadecenol respectively, which raised to 44.34% by acetylation. Epoxidation of hydrocarbons yielded 39.4%, 58.58% for cis- 9-octadecene and trans 2-octadecene respectively. - Elemental analysis of fatty 2-morpholinones and 2-oxazolidones was found to be in agreement with the expected structure formula. The results of biological activity show 95% inhibition for the used bacteria (Escherichia coli. Pseudomonas flourescence. Bacillus subtilus and cerieus). and against fungi, {Aspergillus flavus. Aspergillus clavatus and Penicillium notatum). - The results of the present studies lead to the conclusion that, the industrial wastes were successfully epoxidized in the form of (esters, alcohols and hydrocarbons) using commercial epoxidizing agent to give relatively high yield of epoxy compounds. These compounds further utilized in the synthesis of fatty 2-morpholinones and fatty 2-oxazolidones which are known to possess not only biological activities but also useful j ndustrial propertie. |
