Hangzhou Long Chemical Science & Technology Co., Ltd has formed the systematic R&D structure which forms Hanzhou R&D center as a core, takes laboratories of subsidiaries as keys and connects domestic key universities,with fully-equipped devices and wider research range.
We keep the long-term cooperation with every branch of Institute of Chemistry the Chinese Academy of Sciences、Zhejiang University、ZhejiangUniversity of Technology、Department of Chemistry Fudan University、ournal of Organic Chemistry Lanzhou Universit、Shuzhou Chemical Industrial Park.,the introduction of advanced technology and equipment,Independent research and development 、Independent Innovation、 Independent brands.
Have about 60 R&D staff with bachelor's degree, master's degree and PhD degree, covering every aspect of new product development and process improvement
In July 2009, the company established a joint laboratory with Zhejiang University of Technology, thereby consolidating its industry leading position in the scientific innovation.
With fully-equipped devices and wider research range:oxidation、reduction、neutralization、esterification、nitrify、nitrification、acylation、halogenate、hydrolysis、diazotization、Coupling、rectification、molecule distillation.......
R&D Center in Hangzhou and each large subsidiary are scheduled for completion, with fully-equipped devices and wider research range
Through the utilization of “RT base low-temperature liquid-phase catalytic hydrogenation” technology, Sinorgchem reduces the total quantity of production waste water to 98.9%. Sinorgchem achieves the zero emission of the waste water in the whole production process through waste water disposal installment and biochemistry processing.
Simultaneously all gas waste produced in the production process goes through recycling set, emitted after chemical procedure and concentrately, greatly reduces the pollution.
