Abstract

1,243,313. Organic peroxides. PENNWALT CORP. 20 Feb., 1970, No. 8229/70. Heading C2C. Organic peroxides are produced by reacting (1) an olefin of general formula in which y is 1, 2 or 3; R<SP>1</SP> is a mono-, di- or trivalent aromatic radical depending on the value of y; R<SP>2</SP> and R<SP>3</SP> are each H, or an aliphatic, cycloaliphatic or aromatic radical; R<SP>4</SP> is an aliphatic or aromatic radical; with the provisos that R<SP>2</SP> and R<SP>3</SP> may be joined together to form a cyclic group; R<SP>4</SP> and either R<SP>2</SP> or R<SP>3</SP> may be joined together to form a cyclic group; R<SP>4</SP> and R<SP>1</SP> may be joined to form a fused ring group; R<SP>2</SP> or R<SP>3</SP> may be joined to R<SP>1</SP> to form a fused ring group; and when R<SP>1</SP> carries substituents at least one ring carbon atom ortho to a is unsubstituted; with (2) a halide of formula in which X is I, Br, C1 or F; and (3) an organic hydroxperoxide of the general formula in which R<SP>5</SP> is an aliphatic or cycloaliphatic radical, the reaction being carried out under substantially anhydrous conditions, in the absence of free acid, the relative amounts of reactants (1) and (3) being such that the mole ratio of-OOH groups in the hydroperoxide to ethylenic double bonds in the olefin is from 1À 1:1 to 2: 1. Examples are given of the preparation of dicumyl peroxide; 1,4-bis[a-(t-butylperoxy) - isopropyl]benzene and 4 - [a - (t - butylperoxy) isopropyl] - α,α,α<SP>1</SP>,α<SP>1</SP>- tetramethyd naphthalan. This latter compound is preparelby reacting 1,2,4 tris (a-hydroxy isopropyl) benzene with hydrochloric acid to give 4-(achloroisopropyl) - a,a,a<SP>1</SP>,a1 - tetramethylnaphthalan which is reacted with t-butylhydroperoxide and 4 - isopropenyl - α,α,α<SP>1</SP>,α<SP>1</SP>- tetramethyl phthalan. A list of peroxides made by the process of the invention is also given and this includes peroxides carrying a chlorine or fluorine substituent.
