| Description |
Studies on surface reactivity of substrate iron (Fe-particles) were made in the tribo-chemical
environment of alkyl oetadecenoates. Two alkyl octadecenoates namely ethyl octadecenoate and methyl
12-hydroxy octadecenoate, slightly different in their chemical nature, were taken for preparing the
chemisorbed reaction films (CRF) at the temperature 100:t 5°C. The reaction products collected in the
composite (amorphous) phasc were isolated into three different solvent-soluble fractions (sub-layer
films) using polar solvents of increasing polar strength. The FTIR analysis of these films showed that
these were primarily organic in nature and were composed of alkyl and/or aryl hydroxy ethers, unsaturated
hydroxy ketones, and aromatic structures chemically linked with iron surface. These reaction films
also contained large amount of iron (Fe). Further, these film fractions also showed varying thermal
behaviour during thermal decomposition in the temperature range of 50-800°C when thermally evaluated
in the nitrogen environment.
