A literature survey is presented concerning the properties of tall oil, the theory of catalysis, and catalytic hydrogenation applied to tall oil. It is the purpose of the experimental work to prepare a material from tall oil by hydrogenation which will lend itself more useful as a sizing agent for certain low grades of paper.
The experimental results indicated that by hydrogenating tall oil soap, a whiter, less oily material is obtainable. Handsheets were prepared using this hydrogenated material, the starting material, and rosin size as sizing agents. It was found that the handsheets sized with the hydrogenated material had a higher brightness than those sized with the non-hydrogenated tall oil soap. The strength of sizing of the hydrogenated versus the non-hydrogenated sized paper was not appreciably changed.
