НСІ ZnCl2 2,4-dimethyl-3-pentanol

Answer 1

Chemical Name	Mass/Volume used	Moles	Chemical Properties	State of Matter	Safety from MSDS
2,4-dimethyl-3-pentanol	116.2 mg	0.001	Flammable liquid, acute toxicity,	liquid	It irritates the skin, and damages the eye upon contact. The vapor should not be inhaled as it affects the respiratory system
Hydrogen chloride	1 drop of 37 % HCl	0.0012	corrosive	liquid	It causes severe skin, eye burns. It is harmful if swallowed. The vapor should not be inhaled as it affects the respiratory system
Zinc chloride	136 mg	0.001	corrosive, toxic, acute hazard	solid	It causes severe skin irritation, eye burns. Harmful if swallowed. It may damage respiratory system.

It is separated and purified by fractional distillation technique. The purity is checked by ¹H NMR; In the starting material the OH proton signal would be present whereas it is absent in the product. The rest of the signal pattern is same with the starting secondary alcohol.

The reaction is as following tznug Zn2/HCL 4 OH for tho + Zulu
