The solid-state halogenation of naphthalene is more selective than a liquid-phase reaction. It … In each case, we will look at ethene as typical of all of the alkenes. Selected six kinds of polycyclic aromatic hydrocarbons (PAHs) (naphthalene: NA, phenanthrene: (PHE), anthracene (ANT), fluoranthene (FLR), pyrene (PYR), and benzo[a]pyrene (B[a]P)) were exposed to natural sunlight under simulated tidal flat conditions, to check possibilities for photochemical productions of halogenated derivatives in the coastal environment. Naphthalene, camphor, glycerol, or turpentine will react violently with chromic anhydride [Haz. This organic chemistry video tutorial discusses the electrophilic aromatic substitution sulfonation reaction of nitrobenzene, toluene, phenol, naphthalene, and aniline. A mechanically activated solid-state reaction of halogenation of naphthalene with a Pb(OAc)4—alkaline or alkaline-earth metal halide system was carried out to yield 1-halonaphthalene as the main reaction product and 1,4-dihalonaphthalene. Simple reactions involving halogens. ... Naphthalene also undergoes addition reactions more readily than benzene. This is called halogenation. The ambient temperature is constant along the length of the reactor. Chem. They can react exothermically with bases and with diazo compounds. 1,4-Dibromonaphthalene is efficiently converted to the corresponding methoxy (12 and 13) and cyano (14 and 15) derivatives of naphthalene. The pressure is 1 atm and the partial pressure of naphthalene is varied between 0.01 atm and 0.02 atm. Photolytic bromination of tetralin and subsequent double dehydrobromination of 1,1,4,4-tetrabromo-1,2,3,4-tetrahydronaphthalene (10) gave 1,4-dibromonaphthalene (11) as the sole product in a high yield. The addition of molecular chlorine to a number of simple naphthalene derivatives has, therefore, been investigated under a wide range of experimental conditions. Data 1967. p 68]. Reactions where the chlorine or bromine are in solution (for example, "bromine water") are slightly more complicated and are treated separately at the end. The direct halogenation of aromatic hydrocarbons with the aid of suitable catalysts provides a convenient method for the preparation of aryl chlorides and bromides. Oxidation of Naphthalene to Phthalic Anhydride The oxidation is to be carried out in a packed bed reactor with cooling. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
