This process involves heating the oil to a temperature of 250OC in the presence of catalyst such as sulphuric acids, phosphoric acids, clays and metal oxides under an inert, atmospheric or vacuum condition. | Effects of sodium bisulphate catalyst on the dehydration of castor oil for the paint industry International Journal of Mechanical Engineering and Technology IJMET Volume 10 Issue 03 March 2019 pp. 353 363 Article ID IJMET_10_03_036 Available online at http ijmet JType IJMET amp VType 10 amp IType 3 ISSN Print 0976-6340 and ISSN Online 0976-6359 IAEME Publication Scopus Indexed EFFECTS OF SODIUM BISULPHATE CATALYST ON THE DEHYDRATION OF CASTOR OIL FOR THE PAINT INDUSTRY Angela O. Mamudu Enobong A. Charles Francis Elehinafe Olayemi Odunlami and Damilola Akinneye Department of Chemical Engineering Covenant University Nigeria ABSTRACT Crude castor oil seems to have many industrial applications. However its Iodine value range Effects of Sodium Bisulphate Catalyst on the Dehydration of Castor Oil for the Paint Industry angiosperm including the species of great economic importance such as rubber tree Hevea Brasilens and Cassava Manihot Esculenta 1 . Although Castor bean is very useful it is also considered one of the deadliest natural poison ever known to man due to the presence of ricin a very toxic substance to human animals including insects. Its species include Gibsonii Carmencita pink Carmencita Bright Red Impala Red Spire and Zanzibarensis 2 Castor oil is commonly found in the South Eastern Mediterranean region Eastern Africa and generally in the tropical and subtropical regions of the world 3 4 5 and 6 .Currently India is the world s leading producer and exporters of castor seed. Other major producers include Brazil China Paraguay and Ethiopia 7 . In Nigeria castor plant can be found growing in Lagos Ogun Enugu Ebonyi and most commonly in the North region Daily Trust Newspaper 2018 . The percularity of castor oil is due to the presence of the hydroxyl fatty acid known as ricin-oleic acid C18H34O3 an 18- carbon hydro-xylated fatty acid having initially only one double bond 8 . Generally Castor oil consist of ricin-oleic acid .
