Weifang Yixing Chemical Sci&Tech Co.,Ltd is a high and new technology enterprise. With registered capital of 20 million USD, our first project now has annual output of 50000T capacity for sec-butyl acetate(CAS NO.105-46-4) with more than 99.5% purity. It is self-research resources comprehensive utilization project with independent intellectual property rights and international leading level of technology. New production method, instead of traditional esterrification, which is eco-friendly, non-hazardous and pollution-free ,makes sec-butyl acetate much more cost-effective. We will continue to work towards our objectives “green and environmental awareness; science and technology innovation; sustainable development” and make every efforts to be eco-friendly solvent base in China and even all over the world.
