Peroxy acids, hazard

Organic peroxides are used as telomerization catalysts, in spite their potential instability and handling hazards. Telomerization processes patented by Hoechst use bis(trichloroacryloyl)peroxide [72], (C F2 +i COO>2 [73], or bis(4-r-butylcyclohexyl)peroxydicarbonate [74] as a telomerization catalyst. Peroxy-acids of the formula C X2 +i C(0)OOH, where X = H, F, or Cl and n = 1-12, have been claimed in Kali-Chemie patents [75].

Consider the case of the production of peroxy esters (e.g. tert-buty] peroxy 2-ethyl hexanoate), based on the reaction between the corresponding acid chloride and the hydroperoxide in the presence of NaOH or KOH. These are highly temperature sensitive and violently unstable, and solvent impurities are detrimental in their applications for polymerization. Batch operations to produce even 1000 tpa will be unsafe. A continuous reactor can overcome most of the problems and claims have been made for producing purer chemicals at lower capital and operation cost the use of solvent can be avoided. Continuous reactors can produce seven to ten times more material per unit volume than batch processes. Since the amount of hazardous product present in the unit at any given time is small, protective barrier walls may be unneccessary (Kohn, 1978).
