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 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
1, 2, 4 - trichlorobenzene are widely used in the pesticides synthesis. They can synthesize the pesticides dicamba, mites sulfone, sodium pentachlorophenol, PCP, etc. In recent years, many courtiers are trying to develop its downstream product application. High purity 1, 2, 4 trichlorobenzene become the popular fine chemicals and intermediates in international pesticide market, The early 1990s, the World 1,2,4 trichlorobenzene mainly rely on ineffective body processed into mixed trichlorobenzene,mixed trichlorobenzene production of about 50,000 t / a, as the disabled, and restricting the use of lindane, the traditional of trichlorobenzene dwindling raw materials, while developed countries and regions, the production of organic chlorine cautious, a lot of demand from developing countries to purchase, so the current global trichlorobenzene, 1,2,4 especially in high-purity - trichlorobenzene supply triphenyl bismuth. The current global 1, 2, 4 trichlorobenzene market demand of about 3.5 million over the next few years will be 10% of the average annual rate of increase. Foreign raw materials, production of organic chlorine reduction, the Chinese 1,2,4 - trichlorobenzene, the development of production provides a good opportunity for development. One of the most promising process route for the chlorination of p-dichlorobenzene and 2, 4 - dinitro chloro benzene chlorination, dichlorobenzene China has developed rapidly in recent years to provide high purity o-dichloro- the product. Also, China has become the world's largest pair, o-chlorinated benzene producer-product each year a large number of 2, 4 dinitro chlorobenzene, trichlorobenzene, China can provide high-quality rich low-cost production raw materials, China is currently in the process route has been able to produce. O-cresol in the pesticide industry mainly for the synthesis of efficient herbicides, China is only a few producers of coking coal tar fractionation by the product, quality and quantity can not meet domestic market demand. O-cresol herbicide and pesticide intermediates downstream product demand is relatively stable. 2010 China's demand for o-cresol is about 1 million t / a or so, and imports increased year by year, mainly from Europe and Japan. Abroad, mainly o-cresol phenol alkylation continuous production, but China has successfully developed the phenol alkylation technology, which is the method associated key outputs 2,6 - dimethyl-phenol, the use of this technology development 5000t / a production unit. Catechol is an important new type of low toxicity and efficient carbamate pesticide carbofuran, propoxur, Diethofencarb intermediates. Carbofuran is highly toxic organophosphate pesticide alternative low toxicity and high efficiency of the leading pesticide products; other non-absorption of propoxur pesticides, fumigation has a good effect, efficacy and dichlorvos close, but the toxicity is very low, is recommended by the world health organization and storage of pest control household pests in the varieties of Pharmacy. The product is long-term vacancies in China, after 2000, technology breakthroughs, there are two enterprises to build production plant with an annual production capacity of about 2000t / a. Catechol imports mainly from France and Italy. Catechol is produced by mainstream Chinese pesticide varieties of pesticides, pesticide industry, consumption of catechol in 2008 of about 8000t, 2010, the domestic market demand of catechol to 12000t / a of about. In 2002 China's imports of catechol originating in the EU anti-dumping measures taken, which gives catechol industry and opportunities. Nonylphenol is a multi-purpose non-ionic surface active agent, is the largest in the alkylphenol products, petroleum chemical industry and organic synthesis industry, one of the most important intermediates. Excellent decontamination, wetting and penetration, dispersion, solubilization emulsifying properties 10-hydroxydecanoic acid, is widely used pesticide emulsifier. In recent years, rapid development of China nonylphenol, there are more than 10 manufacturers, with a total production capacity of about 60,000 t / a, but most of the production of poor product quality, and are subject to the constraints of raw materials and downstream products, the larger, Therefore, the operating rate of the production company a serious shortage. M-cresol is mainly used for synthetic pesticides. In recent years, production and development of China-cresol downstream synthetic pesticides has broad prospects. The market demand for m-cresol will maintain an average of 8% to 10% of high growth. China has about 10 sets of production equipment produced m-cresol, due to technical and other factors, has less than 60% capacity utilization. M-cresol in the field of pesticides, steady growth in demand, domestic market demand in 2010 to 18200t / a of about. There are currently imported from abroad 7000t / a or so, mainly imported from the United States. In view of the Chinese market remains positive, the next medium-sized petrochemical producers can take advantage of isopropyl toluene own resources to build a million tons / year of toluene oxidation of isopropyl-cresol production equipment and technology to introduce the main technical sources to the United States-based companies, must pay attention to raw materials and downstream pesticide products matching problem.
