Product Description

Good quality 1-bromopropane CAS 106-94-5

1-Bromopropane is colorless or light yellow transparent liquid, neutral or slightly acidic, sensitive to light, mp-110°C, bp71°C, relative density 1.357 (20°C), n20D is 1.4341, can be in any proportion with alcohol Ether mixture, slightly soluble in water. As a raw material for organic synthesis, 1-bromopropane is used in the synthesis of organophosphorus insecticidal acaricides such as fluprophos, prothiophos, profenofos, etc. It can also be used in medicine, dyestuffs, perfumery industry, and as a grid. The reagent material, CAS number is 106-94-5. There are mainly two methods for preparing 1-bromopropane. It is derived from the reaction of n-propanol with hydrobromic acid. Hydrobromic acid was added to concentrated sulfuric acid, n-propanol was added, and the mixture was heated under reflux for 0.5 h. The resulting bromopropane was completely distilled off at 70-75°C, then washed with concentrated hydrochloric acid, and neutralized with sodium carbonate to a pH of 7. Dry with anhydrous sodium sulfate, filter, and distill the filtrate. Collect 69-74°C fraction to obtain bromopropane. It is derived from the reaction of n-propanol with sodium bromide. The n-propanol and water and sodium bromide are heated together to reflux, and sulfuric acid is added dropwise at 69-72° C. After the addition, the reflux is continued for 2 h. Distillation, collecting 68-100 ° C distillate, washed with sodium carbonate solution to neutrality, and then distilled to collect 68-76 ° C distillate propyl chloride. In addition, bromopropane can also be prepared by reacting n-propanol with bromine in the presence of red phosphoru.

In addition, bromopropane can also be prepared by reacting n-propanol with bromine in the presence of red phosphorus.

use
For synthetic pharmaceuticals, pesticides, dyes, spices and so on.

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 uut 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.
