9-Fluorenone Usage

1. 9-fluorenone is an important organic synthesis intermediate, which can be used in the manufacture of a variety of fine chemicals, mainly used in synthetic polymer materials, bisphenol hydrazine, mercapto benzoxazine resin, acrylate resin, polyester, Modifier for polycarbonate and epoxy resin.

2. In the laboratory, hydrazine is used as a raw material, dimethyl sulfoxide is used as a solvent, is used as a catalyst, and oxygen is used as an oxidant. The oxidation reaction is carried out by a tower-type packed reactor, and the reaction liquid is cooled and filtered to obtain a crude content of 93%.

3. The fluorenone, the filtrate is distilled to recover 94% of the solvent and part of the crude ketone. The crude ketone is further purified by directed crystallization to obtain a yellow flavonone having a purity of 99.8% or more.

Notice

1). In the spraying fertilizer period, the cotton boll craze should not early than 60, in case of affecting output and quality.

2).Rainfall after spraying fertilizer will affect the effect, so you'd better notice the weather report.

3). If the product is eaten, absorbed or touched by mistake, it will harm to health and you should go to hospital at once. If it touches skin or eyes, you must wash in clean water immediately.
