1.390 Ufs per 1 K&s gross production. About 475,000,000 Kea, will be saved
per year by utilizing cheaper raw materials. The working productivity
has to,be increased by about 6 times as.compared.with.the average produc-
'tivity of the.total chemical production in 1958. By 1965, the scarcity
of phenols during recent years.-will be overcome,:since plants producing
phenols by the sulfonation method with a yearly capacity of 10,000 t, and
by the cumene method with yearly capacity of 20,000 t will.be erec,ted;
this.phenol will be used primarily for the production of caproladtam
(15,00.0 t,per year). Moreover, a plant producing ethylene glycol, (10,001O."t,
per~year) by direct oxidation of ethylene without-chlorine, two. plafits.~-
producing synthetic detergents (20,000 t alkyl aryl sulfonate6, propylene.
~a n acetylene.,
