Abstract

Przedmiotem zgłoszenia jest sposób utleniania geraniolu w obecności katalizatora, polegający na mieszaniu geraniolu z katalizatorem w ilości od 0,5% wag. do 5% wag. w stosunku do geraniolu pod ciśnieniem atmosferycznym, z intensywnością mieszania 500 obr./minutę, w atmosferze tlenu podawanego z butli przez bełkotkę stosując przepływ tlenu 40 ml/minutę, w czasie od 15 minut do 360 minut. Istota wynalazku charakteryzuje się tym, że jako katalizator stosuje się proszkowy diatomit Proces prowadzi się w temperaturze 70°C - 100°C. Korzystnie stosuje się proszkowy diatomit o składzie: K 0,159%, Ti 0,119, Fe 0,849%, Al 1,116%, Si 37,272% i Ca 0,403%. Korzystnie do reaktora szklanego wprowadza się w pierwszej kolejności geraniol, później katalizator, na samym końcu doprowadza się tlen przez bełkotkę.The subject of the application is a method of oxidizing geraniol in the presence of a catalyst, consisting in mixing geraniol with a catalyst in an amount from 0.5% by weight to 5% by weight of geraniol at atmospheric pressure, with a stirring intensity of 500 rpm, in an atmosphere of oxygen supplied from a cylinder through a sparger using an oxygen flow of 40 ml/minute, for a time from 15 minutes to 360 minutes. The essence of the invention is characterized in that powdered diatomite is used as the catalyst. The process is carried out at a temperature of 70°C - 100°C. Preferably, powdered diatomite with the composition: K 0.159%, Ti 0.119%, Fe 0.849%, Al 1.116%, Si 37.272%, and Ca 0.403% is used. Preferably, geraniol is introduced into the glass reactor first, then the catalyst, and finally oxygen is introduced through a sparger.
