Most products of Fluorine-containing Benzonitrile is a colorless transparent liquid and has a pungent odor. It was widely used in pesticides, pharmaceuticals liquid crystal material manufacturing. High efficiency, low toxicity and residue characteristics. Through extensive research and production practice, we have found some good manufacturing processes of fluoro-containing cyanophenyl products. In addition, we have groundbreaking research on ratio of raw materials, solvent selection, the choice of solvent concentration, related use of catalysts..

Feeding ducks to lay eggs
If the shape of the egg is abnormal and small, it means that the nutrition is insufficient. It is necessary to feed the protein-rich feed such as bean cake, peanut cake, and fishmeal to increase the content of crude protein in the diet to 20%, and to appropriately increase the total amount of the diet; eggshell Thinning, translucent, with trachoma, rough or soft shell, indicating poor feed quality, especially calcium deficiency or vitamin D deficiency, should add bone meal, shell powder, lime powder and other minerals and vitamin D rich feed; Reduced egg weight can increase cod liver oil and inorganic salt additives; if egg production time is concentrated at 2 AM, it means that the feeding is appropriate. If the egg production is delayed every day, and the egg becomes smaller, the feed must be fed.
