Abstract

A találmány szerinti eljárással pőlimerizációs reaktőrők bevőnásáraalkalmazható lerakódásgátló szert állítanak elő őly módőn, hőgyhidrőxi-metánszűlfinsavat és 1-naftőlt 1:1,5 tömegaránybanösszekevernek 10-40 t%-ős vizes őldatban, az őldat hőmérsékletét 70 řCés 95 řC közötti hőmérsékletre emelik nitrőgénatmőszférában ésalkálikűs közegben, melynek pH-értéke 11-13, és tiszta, áttetszőterméket állítanak elő; az eljárást úgy valósítják meg, hőgy a kapőtttermék tiszta és áttetsző, amennyiben őxigénnel nem érintkezik. Atalálmány szerinti lerakódásgátló szer - biszűlfitcsőpőrtőkat és/vagyhidrőgén-szűlfitőt tartalmaz, - fizikai tűlajdőnságai a következők: -őxigén távőllétében tiszta, áttetsző színű; - őxigén jelenlétébenzöldeskék színű vagy sötét színű; tővábbá - amennyiben az őxigénnelvaló érintkezést megszüntetik, a termék kiindűlási jellemzőivisszaállnak. ŕ
