For more than 30 years, it is difficult to imagine how widely castor oil has been used. Dong Yang Oil chemical, in its initial state, is applied to maintain diverse and highly developed technology. Today, castor oil is becoming one of the fastest growing areas in the industry, and related closely to our everyday lives. Castor oil's chemical structure is also maintained even in the field of chemistry that goes through a variety of reactivity and has been attracting attention in many areas. Castor oil derivatives are now widely used in various industries and can possibly compete on the same level with the petrochemical industry. Physical environment-friendly, ecological and recycling aspects have been evaluated as good.

  Castor oil?

Castor near the equator to grow well in hot, dry regions and is grown as a yearling or a perennial. India in the world, Brazil is the most important plantation addition, China and Southeast Asia are also some cultivation. Castor oil content of seeds is about 45-55% of the extrusion and solvent extraction in a manner which can be obtained. This produced a very wide range of oils are being used commercially, that's why receivers commonly known as ricinoleic acid : cis-9, 12 Hydroxy octadecanoic acid hydroxide, the unsaturated fatty acid content caused by the specific physical and chemical unique This is because the nature.

  Castor oil's chemical structure

  Castor oil fatty acid carbon number distribution and characteristics of

Fatty acidAverage content
Ricinoleic acid 85 To 95%
Oleic acid 6 To 2%
Linoleic acid 5 To 1%
Linolenic acid 1 To 0.5%
Stearic acid 1 To 0.5%
Palmitic acid 1 To 0.5%
Dihydroxystearic acid 0.5 To 0.3%
Others 0.5 To 0.2%

These various levels of fatty acids because the presence of environmental factors, the restrictive sampling, analytical errors, and so on will be affected, other than that of the other vegetable oils can be very uniform in composition. Castor oil has the high gravity. It is melted well by highly flourishing solvent such as alcohol, but not by fragrance-type of hydrocarbon such as benzene Changes in viscosity due to changes in temperature are very low, because little left after Incinerate residues are useful in lubricating oil. In addition, polar hydroxy group (-OH) due to the influence of resins, waxes, polymers, etc. are well-mixed paints, inks, resins, etc. are widely used.
