Castor, one of the world’s prime ten oil crops, is of high economic value. Castor oil and its merchandise have a broader worldwide market, due to their particular industrial uses and financial worth.
Refined castor oil may be utilized in aircraft, ships, vehicles and high-precision lathes, in addition to industrial raw materials produced spices, synthetic leather and different products. In recent times, with the always growing demand for castor oil in international market, prices are always improving. Processing castor oil has broad market prospects, and the financial benefit is appreciable. As well as, castor leaves, stems, castor meal, castor shell can be used for growth and production of downstream products, which not solely diminished the cost of manufacturing, but additionally vastly improved the general effectivity of enterprises.
Castor oil has been exploited in very long time in the past, but initially it solely through merely processing, till the 1970s it can be widely developed, as a result of restrictions of natural setting, some international locations had been underutilized castor oil’s production and processing functions. The United States is a vital country of producing castor oil besides the Asia.
Practical groups in the molecular structure of castor oil determine that it could possibly have quite a lot of chemical reactions to produce numerous derivatives, and most of them are important tremendous chemicals, about 200 kinds of varieties, these high value-added merchandise may be utilized in various industrial fields. Within the United States, their application assigned is: refined oil accounted for 48%, dehydrated oil accounted for 20%, sebacic acid manufacturing accounted for 30%, other purposes accounted for two%, the annual consumption of castor oil is about 80kt. Yearly, Japan needs to import 3kt, occupies seventy nine% of the overall amount, primarily utilized in coatings, hardened oil, sebacic acid, surfactants, cosmetics materials and so forth.
Nylon-11 resin is the world’s most popular product, which synthetized through the use of castor oil as uncooked material, widely used in cars, ships, machine instruments, building, army, medical and other industries. Previously, China’s annual demand for nylon-11 resin is about 2,000 tons, to 2010 has reached 5,000 tons. Produce 1 ton of nylon-eleven resin requires about three.5-four.5 tons of castor oil, 5,000 tons of nylon-eleven resin requires about 23 thousand tons of castor oil. Couple with other features of the demand, China’s annual consumption of castor oil was stabilized at 90,000 tons, but Chinese manufacturing was only 50,000 tons, the market hole is about forty,000 tons. So it should present a great market space for Chinese castor oil manufacturing enterprises, additionally offers an enormous market house for the castor plant business.
Castor oil’s molecular structure is containing carboxyl group and unsaturated double bond, can produce a collection of products which obtained from petroleum, so the castor has the identify of “planted petroleum”. In keeping with reports, this know-how is predicated on castor oil insteads of petroleum as raw material, by way of castor oil extraction, catalytic cracking, molecular reorganization, inexperienced chemical synthesis, reconcile and dozens of processes to supply “castor-primarily based biodegradable common engine oil”. This product has good biodegradability, excellent low temperature startability, high-temperature resistant, lengthy life, oil adjustments fewer and save fuel and other traits, enjoyed the “green oil” popularity. In response to reviews, calculated that a car driving 50,000km below regular circumstances, in contrast the lubricant ready by castor oil and petroleum, only a car can save greater than 2,000 yuan of fuel prices in each oil change period.
