Reuse world

September 19 journalists from Liaoning Shixing Pharmaceutical Chemical Co., Ltd understands that the company used self-developed world-advanced level of glyoxylate Production of vanillin clean production technology, hydrogen reduction method and the twin towers Preparation of o-continuous distillation anisidine new technology, EMO compound microbial bacterial pollution of new technologies, the construction of the world’s large 2000 tons / year ethyl vanillin device and its supporting projects on September 18 this year, all built and put into trial production. Trial production output o-Anisidine by the State Quality Supervision and Inspection Center dye test, the content reached 99.53%, exceeding the national standard high grade 0.33 percentage points. Ethyl vanillin fragrance cosmetics by the National Light Industry Products Quality Supervision and Testing Center washing test, aldehyde reached 99.96%, the product quality more than the national standard 1.96 percentage points. This marked ethyl vanillin in China ranks among the advanced industrial production.

According to reports, ethyl vanillin is on a broad spectrum of flavor, is the world’s most important synthetic fragrance is one of the food additive industry, an indispensable and important raw material, can be widely used in food, chocolate, ice cream, drinks, as well as perfumes, cosmetics, daily play by the role of incense and incense set. In addition, ethyl vanillin but also as feed additives, electroplating industry, brightening agents and the pharmaceutical industry intermediates.

2003 World spices and fragrance market, annual sales of just over 150 billion U.S. dollars, in recent years, international markets, spices (refined) market demand for an annual growth rate of 47%, to the end of 2008 is expected to more than 20 billion U.S. dollars. Ethyl vanillin market has long been in short supply. At present, the largest-scale industrial production of ethyl vanillin capacity is only 600 tons / year, the national annual output of less than 2,000 tons.

At present, the production of glyoxylic acid ethyl vanillin are mainly two kinds of law and nitrosyl France, glyoxylic acid method is commonly used foreign technology process route; while nitrosyl France toxic benzene hydroxylamine due to the emergence of countries have already eliminated , only most of our enterprises are still used today.

mostly based abroad, o-ethoxy-ethoxy phenol and glyoxylic acid condensation product -4 - hydroxy-mandelic Acid and then the high-temperature oxidation of copper oxide catalysts in the water decarboxylation way of producing ethyl vanillin. China’s Jilin Chemical Industry Co., Ltd. has successfully developed self-ethoxy phenol and o-nitroso-NN-dimethyl aniline and formaldehyde condensation of ethyl vanillin production process technology.

Liaoning Shixing Pharmaceutical Chemical Co., Ltd is specialized in medicine, pesticide and dye intermediates research, development, production and business of private high-tech enterprises. The company expects a total investment of 124.4 million yuan construction of 2,000 tons / year ethyl vanillin device and its auxiliary works mainly comprise the 10,000 tons / year o-Anisidine devices, 2,500 tons / year guaiacol unit and 2000 tons / years of ethyl vanillin unit.

with the traditional process compared to nitrosyl France, Liaoning Shixing Pharmaceutical Co., Ltd. of the development of new technology of glyoxylic acid, using homegrown o-nitro-chlorobenzene, a non-chlorine ions and pyrocatechol raw materials, the catalyst synthesized by the reaction with chloroethane ethyl wood phenol, was isolated by the distillation of more than 99% of wood-ethyl phenol; ethyl phenol and glyoxylic acid synthesized wood mandelic acid, and then the next one in the catalytic Oxygen oxidation of B acid, decarboxylation obtained after crude vanillin, and then by distillation, crystallization, drying and other refined output of more than 99.9% fine vanillin. This new technology not only to get rid of the N, N-dimethyl aniline and other highly toxic chemicals, the product yield increased significantly (~ 80%), but also greatly improve the operating environment, is also a significant reduction in waste per tonne of product produced water 40 tons, CODcr concentration of about 4000mg / L, although the volume of effluent increased, but significantly reduced the concentration of COD, to overcome the old technology can not be biological treatment of sewage shortcomings.

Liaoning Shixing Pharmaceutical Co., Ltd. with self-produced products of o-nitro-chlorobenzene production of downstream products vanillin, not only greatly extend the industrial chain, to fill the gaps in Liaoning Province, vanillin industry, but also product quality up to the World advanced water products, and the French Rhodia Group, the Norwegian Bao Lige group comparable to promote the Chinese vanillin industry technological advances.

工业生产在中国的乙基香兰素队伍中的先进

9月19日，辽宁世星医药化工有限公司，记者了解到，该公司采用自主开发的世界的乙醛酸生产香兰素清洁生产技术，氢还原法和双塔制备邻氨基苯甲醚新的连续蒸馏技术的先进水平， EMO复合微生物细菌污染的新技术，是世界上大型建设2000吨/年乙基香兰素装置及其配套工程于今年9月18日，所有建成并投入试生产。审判产量邻由国家质量监督检验测试中心染料氨基苯甲醚的含量达到99.53％，超出国家标准高品位0.33个百分点。乙基香兰素的国家轻工产品质量监督检验测试中心测试洗涤，醛香水化妆品达99.96％，产品质量高于国家标准的1.96个百分点。这标志着在中国乙基香兰素队伍中先进的工业生产。

据报道，乙基香兰素的味道是广泛的，是世界上最重要的合成香料是食品添加剂工业，一个不可缺少的重要原料之一，可广泛用于食品，巧克力，冰淇淋使用，饮料，以及香水，化妆品，日常发挥了香，香集的作用。另外，乙基香兰素而且作为饲料添加剂，电镀业，增白剂和制药工业的中间体。

2003年世界香料和香水市场，年销售额仅150多亿美元，近年来，国际市场，香料（精制）为47％的年均增长率的市场需求，到2008年底预计将更多超过20亿美元。乙基香兰素市场长期供不应求。目前，最大规模的乙基香兰素工业生产的能力只有600万吨/年，全国年产量不足2000吨。

目前，乙醛酸乙基香兰素生产主要有两个法律和亚硝基法国，乙醛酸法种常用的外国技术工艺路线;而法国有毒的亚硝苯胲由于国家出现已经消除，只我们的企业大多沿用至今。

大多设在海外，邻乙氧基乙氧基苯酚和乙醛酸缩合产物-4 -羟基扁桃酸，然后高氧化铜催化剂的温度在生产乙基香兰素水氧化脱羧的方法。中国的吉林化学工业有限公司已成功开发自我乙氧基苯酚和邻硝基神经-二甲基苯胺和甲醛的乙基香兰素生产工艺技术的凝结。

辽宁世星医药化工有限公司是一家专业从事医药，农药，染料中间体研究，开发，生产和民营高科技企业的生意。该公司预计的12440.00万2000吨元建设总投资/年乙基香兰素装置及其配套工程主要包括1万吨/年邻氨基苯甲醚装置，2500吨/年愈创木酚装置和2000吨/年乙基香兰素装置。
与传统工艺相比，亚硝基
法国，辽宁世星药业有限公司的乙醛酸的新技术开发有限公司，采用国产邻硝基氯化苯，非氯离子和邻苯二酚的原料，合成催化剂通过与氯乙基木酚反应，分离得到了超过99％的木材蒸馏乙基苯酚，乙基苯酚和乙醛酸合成木材扁桃酸，然后在催化氧B酸，脱羧氧化下一个香兰素后取得原油，再经蒸馏，结晶，干燥和其他超过99.9％的罚款香兰素精制输出。这项新技术不仅得到了N，N -二甲基苯胺等剧毒化学品除掉，产品产量大幅增加（80％），而且极大地改善经营环境，亦是每吨废物显着减少产品的生产用水40吨，CODcr的浓度约为4000mg / L时，虽然污水增加，但大大减少了COD浓度，以克服旧技术卷不能被污水生物处理的缺点。

辽宁世星药业有限公司，拥有自营有限公司生产的产品邻硝基香兰素的氯化苯生产下游产品，不仅大大延长产业链，填补辽宁省，香兰素产业，而且产品质量方面的差距到世界先进水的产品，和法国罗地亚集团，挪威宝丽格组相比，弘扬中华香兰素工业的技术进步。
