As we all know to live in this world we have to perform some activity by which we can earn money. There are many activities by which we can earn money and meet the standards to live in this society. And from one of them is franchise. Franc Small offices have unique needs, and thatincludes document shredding. Designed with the smaller business inmind, the Dahle 20314 is a cross-cut shredder that offers Level 3security and brings you into compliance with federal regulations. The
Chinese castor plants were containing 48.1 ~ 49.37% of oil,5.83 ~ 6.26% of water. France is a big castor oil importer in the world, it monopoly on theproduction technology of nylon 11. In recent years, Franceimports a large number of castor oil from Indiaand China,and then refined into nylon 11 and other important fine chemicals to the world.With the use amount of nylon 11 increased, the international market price wasfast-growing, the market price has reached $12,000, the hose which made ofnylon was $270,000/T, nylon 11 for the automotive industry is the only workablehoses, in the aerospace, automotive, electronics and other cities oil pipelinesalso have large number of applications, it is difficult to find a completelysatisfactory substitute of nylon 11 ina considerable period of time. At present, the price of castor oil on theinternational market has reached $8,000,000/T or more, the annual demand forcastor oil in the world market is 450kt, the total output was 300kt, in a stateof demand exceeds supply. Developed castor industry is a systematic project.In China,the production of castor oil has been decreasing due to castor bean'spurchasing price reduced. In 1999, China's total production of castor oil was 240kt, used in producing sebacic acid has 40kt, other newproduct was developed little amount, most of them are directly processed intoprimary products for exporting. Because of demand exceeding supply, China has beenimporting large quantities of castor oil. Currently, in China, castoroil's processing technology was lagging behind, developed new varieties arevery less, with low yields, small range of applications, and some varieties arestill blank. Therefore, developing deep processing products of castor oil havean important significance on China.From the view of the Chinese market, developing castor production has beenurgent affairs, from the development momentum of view, China can speed up the developmentof a variety of castor oil derivative products. Due to the influence of climatic conditions, India, Brazil'scastor production has been on the decline, coupled with India hasdeveloped the process of manufacturing nylon 11, and it will greatly reduce itsexports of castor oil. Chinanow has 50% of castor beans and castor oil derivatives gap, if China couldmake full use of development advantages, developing castor beans and castor oilderivatives, can be used for export in large quantities. And it will have asignificant role in promoting China'seconomy. One of the most important uses of castor oil is synthesizingsurfactant. There are many synthesis methods, but the method which used at theearliest is enzymatic hydrolysis the grease, under the action of enzymesbacteria, such as lipase or pancreatic enzyme by bio-fermentation principleshydrolyze the grease at room temperature, and the hydrolysis rate is 90%,products are best used for the cosmetic industry, then fatty acid methyl esterthrough ethoxylation, sulfonated or other reactions, it can form of hydrophiliccomponents. At the same time, the ricinoleic acid methyl ester can be preparedpurer derivatives. Fatty acids primary as basic raw material of surfactants hasbeen widely used, fatty acid's application in the international marketsdistributed as: Fatty alcohols, metal soap was accounted for 35~40%, detergent,soap was 30~40%, alkyd resin, paint was 10~15%, rubber, tyres was 3~5%,textiles, leather, paper was 3~5%, lubricants, grease was 2~3%, and other was3~5%. Visible, the biggest application area of fatty acids is in daily chemicalindustry, in the cosmetics material industry also as raw materials for cream. Source:http://www.cosprm.com
