UN 1076 – Phosgene HAZARDS: Phosgene is a highly toxic‚ irritating and corrosive gas. Inhalation can cause fatal respiratory damage. Phosgene reacts violently and decomposes to toxic compounds on contact with moisture‚ including chlorine‚ carbon monoxide and carbon tetrachloride. In case of skin contact: If liquid phosgene (below 8.2 deg C) contacts the skin or clothing‚ an inhalation exposure should be suspected. Hazards due to skin contact with the gas is unknown. Phosgene does‚ however‚ react

was to use gas chromatography to determine the relative amounts of the three components of gas products from the dehydration reaction of 1- and 2-Butanol with sulfuric acid and the dehydrobromination reaction of 1- and 2-Bromobutane with potassium tert-butoxide. E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group‚ which consists of a weak base‚ leaves an organic compound‚ leaving an intermediate carbocation. In the second step‚ a carbon

Comparison of Three Isomers of Butanol SCH 4UI Abstract The Hydroxyl group on alcohols relates to their reactivity. This concept was explored by answering the question “Does each alcohol undergo halogenation and controlled oxidation?” . Using three isomers of butanol; the primary 1-butanol‚ the secondary 2-butanol and the tertiary 2-methyl-2-propanol‚ also referred to as T-butanol‚ two experiments were performed to test the capabilities of the alcohols. When mixed with hydrochloric acid in

In order to have a strong background about the solubility test‚ we first classify organic compounds of known functional group using the said test. Butyl bromide‚ ethanol sucrose‚ butyraldehyde‚ ethanoic acid‚ methyl amine‚ nitrophenol‚ diethyl ether‚ benzoic acid and propanone were used. It is found out that they are class X‚ Sn‚ S‚ N‚ Sa‚ Sb‚ S‚ N‚ A1 and Sn‚ respectively. We use water‚ ether‚ HCl
