Development Of Castor Oil
About 70% of Chinese castor
oil processing factories in stop production or semi-shutdown state, because
there is no adequate, high-quality raw material castor sources. In the end of
1980s, China extends and built several large scale castor oil factories, each factory's
total amount of annual output of castor oil are in 10 -15 thousand tons, total
output capacity is about 55,000 tons per year.</a>
In Chinese [ ] products, there are about 30,000 tons achieve international 1st
standards quality every year, products produced by castor oil have about 30
species, mainly have hydrogenated castor oil, sebacic acid, dehydrated castor
oil, tour trung quoc 12-hydroxy stearic acid, acetyl epoxidized castor oil methyl ester, Turkey
red oil, hendecene acid, etc. In the international market, the main importing
countries of castor oil are the industrialized countries, such as Britain, France,
USA, Japan, Germany and so on.
The world's major markets of castor oil were
concentrated in North America and Europe, of which the France, Britain,
Netherlands, United States, Germany, five countries accounted
for 61% of annual fuel consumption.
India castor oil used in making soap has about
1.6-1.8 million tons, the textile industry use 2-3 thousand tons, chemical
industries use 2-3 thousand tons, lubricating oil use 5-6 thousand tons, the
rest for kynghidongduong.vn exporting. In Japan's castor oil use amount, paints accounted for
28.6%, surfactant is 12.3%, [ ] is 8.2%, resin is 5.7%, hardened oil is 17.8%, sebum oil is 12.9%, others
is 14.5%. Japan needs to import large quantities of castor beans every year,
they are mostly imported from China, Pakistan, Indonesia, Sri Lanka,
Philippines, Vietnam, Ethiopia, Brazil and other countries. Castor oil in the United States
for the production of plastics and resins was accounted for 25.9%, fatty acids
accounted for 12.7%, lubricating oil accounted for 6.3%, paint accounted for
23.7%, cosmetics (mainly synthetic waxes) accounted for 2.1%, others such as
inks, surfactants accounted for 29.1%, these castor oils are imported from
foreign countries.
Every year, the world needs 700 thousand tons of
castor oil, convert into 1.6 million tons castor beans. Nowadays, gasoline
resource was gradually reduced, transportation, live used gasoline was rapidly
increasing, use gasoline as a raw material for synthetic material will be
increasingly constrained in cost. And the United States study found that
long-term exposure to polymers which synthesized by gasoline was harmful to
human health. California and a number of other states have enacted laws and
regulations for this, to restrict and gradually prohibit using synthetic resin in
city buildings, interior facilities and human health-related sites and articles,
which is polymerized from petroleum, natural gas cleaved into monomers raw
materials, it makes castor oil's demand was rising sharply.
Castor cultivation in China is very commonly, there is no
obvious planted regional division. South from Hainan
Island, north to Heilongjiang is cultivated. Because castor
hybrids with drought resistance, thin ridge resistant, saline-alkaline
tolerance, well-adapted, simple to manage, less invest, high efficiency and
other salient features, no matter grain field or hills, hilly land[ ],
saline-alkali soil and even around the house can be grown it. So anywhere in China
can be planted castor.
