production method
By aniline diazotization, replacement derived. Add 30% hydrochloric acid and aniline to water, stir and cool to 2°C, slowly add sodium nitrite solution, and control temperature not to exceed 12°C. When the last part of the sodium nitrite solution was added dropwise, it was tested with a potassium iodide starch test paper. The reaction was blue and the diazotized solution was obtained. The potassium iodide solution was added into the diazotizing solution in multiple portions. At this time, nitrogen was released and allowed to stand for 2 hours until no nitrogen gas escaped. After cooling, the aqueous upper layer was separated. Add 10% sodium hydroxide solution to the reaction solution to pH14. Steam distillation was performed, and the distillate was separated into aqueous layers. After drying, it was subjected to atmospheric pressure fractionation. The 184-188°C fraction was collected, which was iodobenzene, with a yield of 77%.

Product expansion
1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.
2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period, it can not be taken directly by patients.
3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.
4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.
5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
