What are the ir structural frequencies of epichlorohydrin?
The infrared (IR) structural frequencies of epichlorohydrin include a strong absorption band around 2930-2980 cm^-1 for aliphatic C-H stretching, a medium absorption band around 1330-1380 cm^-1 for C-O stretching in the epoxide ring, and a strong absorption band around 1030-1090 cm^-1 for C-Cl stretching. These frequencies can vary slightly depending on the specific molecular environment of the molecule.
How is glycerol formed?
There are two basic ways glycerol forms. The first is natural, by the combinaation of fats and oils. The second is by sythesizing it, by a cehmical process that begins by chlorinating propylene, which gives allyl chloride, which is oxidized with hypochlorite to dichlorohydrins, which reacts with a strong base to give epichlorohydrin. Epichlorohydrin is then hydrolyzed to give glycerol.
How is Epoxy resin made?
Firstly at 50⁰C in a conventional reactor, mix the reactants (epichlorohydrin and bisphenol A) under a molar ratio of bisphenol A to epicholorhydrin 1:14, then raise the temperature to 115⁰C over a period of time of 30 minutes. Conduct this reaction under a nitrogen gas environment. Secondly add an alkaline catalyst (2 moles of NaOH), as 30% aqueous solution, drop wise. This usually takes several hours. The rate of addition is maintained as such the reaction mixture does not change the colour when phenothalein (an indicator) is added. Thirdly carry out the reaction for an additional 30 minutes and then wash out the excess catalyst. Next raise the temperature to 130⁰C and remove water by decanting (The remaining liquid is dried with anhydrous sodium sulfate or other dessicant) Lastly remove excess epichlorohydrin by vacuum distillation.
How do you convert chlorobenzene into phenol?
You hit it with steam, and it will hydrolyze into phenol and hydrochloric acid. This isn't a real common way of making HCl, though; the chloralkali process that gives us sodium hydroxide also throws off hydrogen and chlorine, which can be mixed and exposed to UV light to give HCl. But as an educational setup, it's fine. Most people get their phenol the old-fashioned way, by oxidizing isopropylbenzene. A big reason for doing it that way is the byproduct of the reaction is acetone. If you condense acetone and phenol, you get bisphenol a, which is required if you want to make either polycarbonate (by reacting it with phosgene) or epoxy (by reacting it with epichlorohydrin). 'Course, you can also sell the acetone and phenol separately because there is great demand for both chemicals.
Chemistry in agriculture field?
Since chemistry engages in the composition, properties, and reactions in matter, especially elements, it can help agriculture in that through chemistry we can create new substances to improve our crops, their quality, productivity, and resistance to pests and time. Also through chemistry, accurate proportions of the chemicals used are determined, and the right substances for the crop are known. Hence, chemistry improves agriculture.
What is the density of Epichlorohydrin in pounds per gallon?
The density of epichlorohydrin is approximately 8.6 pounds per gallon. This value can vary slightly depending on temperature and purity, but it generally remains in this range. Always refer to the material safety data sheet (MSDS) or manufacturer specifications for the most accurate information.

Does water form an azeotrope with epichlorohydrin?
A simulation in SimSci Pro/II simulator using the NTRL Liquid Activity method at 14.696 psia for 1-chloro-2,3-epoxypropane (epichlorohydrin) and water indicates that they do not. The T-x-y diagram and equilibrium x-y diagrams do not show an azetrope forming at any point. As a side note these two chemicals should be insoluble in one another so you would not generally expect an azeotrope to form. See the link for an image of the equilibrium graphs.

What are three uses of chlorine?
Manufacture of Epichlorohydrin which is then used to make epoxy resins.Manufacture of TiCl4 which is then used to make TiO2 a key pigment in paint manufacture and with other uses. TiCl4 is also reacted with sodium metal to produce titanium sponge which is used in aerospace.Manufacture of Phosgene which is used to manufacture isocyanates and polyurethanes.

What some things chlorine is used in?
HI! (chlorine is a gas) Principal applications of chlorine are in the production of a wide range of industrial and consumer products. For example, it is used in making plastics, solvents for dry cleaning and metal degreasing, textiles, agrochemicals and pharmaceuticals, insecticides, dyestuffs, household cleaning products, etc. Quantitavely, about 63% and 18% of all chlorine are used in the manufacture of organic and inorganic chlorine compounds, respectively, and about 15,000 chlorine compounds are being used commercially. The remaining 19% is used for bleaches and dissifection products. The most significant of organic compounds in terms of production volume are 1,2-dichloroethane and vinyl chloride, intermediates in the production of PVC. Other particularly important organochlorines are methyl chloride, methylene chloride, chloroform, vinylidene chloride, trichloroethylene, perchloroethylene, allyl chloride, epichlorohydrin, chlorobenzene, dichlorobenzenes, and trichlorobenzenes. The major inorganic compounds include HCl, Cl2O, HOCl, NaClO3, chlorinated isocyanurates, AlCl3, SiCl4, SnCl4, PCl3, PCl5, POCl3, AsCl3, SbCl3, SbCl5, BiCl3, S2Cl2, SCl2, SOCI2, CIF3, ICl, ICl3, TiCl3, TiCl4, MoCl5, FeCl3, ZnCl2, etc. IT IS WIDELY USED IN PURIFING WATER. if you like my answer please send me message at lovely zoya zoya facebook.com GOOD LUCK!
