Production     


The company headquarters has
one multi-function pilot plant and 3 multi-function production plants,
and covers an area of 40,000 square meters.
The production base is of 112,000 square meters.
In the plant there are 180 reactors with different capacities, covering a total capacity of 330,000 liters with smallest 100 liters and largest 5000 liters.
The processing temperature, ranging from low temperature of less than -100¡æ to high temperature of more than 240¡æ, is applied to more than 20 organic chemical reactions, Grignard reaction, Wittig reaction, Organic metal reaction£¬Palladium-Catalyzed Cross-Coupling Reactions, and so on.

The reactors with different capacities, the advanced productive technology and high production capacity are able to satisfy the customers¡¯ demands ranging from one kilogram to one hundred tons.
The production capacity in Valiant:
55 tons of liquid crystal component,
210 tons of liquid crystal intermediates,

Hydrogenation plants, have 16 high-pressure hydrogenation autoclaves with a gross capacity of 21,000 liters, a maximum pressure of 26 mPa and a maximum temperature of 250¡æ. These plants provide high-quality, multi-variety and large-batch hydrogenation products.

The excellent public facilities and post-processing equipments not only ensure the product quality but also protect the environment, ensure safety and clean production, and establish an integrated and advanced production system.
