Dehydrated Castor Oil Fatty Acid commonly known as DCOFA is a high diene Fatty Acid based on Castor Oil. Three types of DCOFA are offered depending on the conjugation (low, medium and high). DCOFA is liquid at room temperature, having a water-white to pale yellow colour. Dehydration of Castor Oil is carried out at about 250o C in the presence of catalysts (e.g., Concentrated Sulphuric Acid, Activated Earth) and under an inert atmosphere or vacuum. Under this condition of dehydration, the Hydroxyl Group and adjacent Hydrogen Atom from the C-11 or C-13 position of the Ricinoleic Acid portion of the molecule is removed as water. This yields a mixture of two acids, each containing two double bonds but in one case, they are conjugated.

ApplicationsDehydrated Castor Oil Fatty Acid based Alkyd Resins and Polyamides make up superior constituent in numerous paint and printing inks formulations. Styrenated Epoxy Esters of these Fatty Acids are used in prime quality Automotive Paints. DCOFA is also used in the manufacture of High Aolid Alkyds, Acrylic and Epoxy Ester Resins, which are useful for interior and exterior can coatings, appliance finishes, automotive topcoats, primers, coil coatings, tube coatings, marine finishes, overprint varnishes and high-speed printing inks. Furthermore DCOFA can be used as chemical intermediate because of their conjugate dienes structure.

CASTOR DE-OILED CAKE is obtained during the crushing of Castor Seeds to extract oil.

Applications

• The de-oiled cake is an excellent environment friendly, organic fertilizer which contains 5% nitrogen, 2% potash and 1% calcium.
• It improves soil fertility and productivity and helps in increasing the nutrient uptake by plants.It is also known to protect the plants from Nematodes and Termites.
• It is also used as fuel in boilers as it is economical and has a higher calorific value than other fuels.
• Detoxified Castor Cake can be used as an animal feed.
