Abstract
Abstract A method and apparatus for conducting chemical reactions in polyphase systems by using emulsifying means for the liquid components consisting of ultrasound emitters or turbines, in the absence or presence of a solid catalyst in fixed bed form with which the emulsified liquid components are brought into immediate contact by continuous circulation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
75 words
A method of conducting chemical reactions in polyphase systems, comprising the steps of: emulsifying liquid components, which consist of at least two partially or totally immiscible liquids, with an ultrasound emitter or a turbine; continuously circulating said emulsified liquid components; and directly contacting said emulsified liquid components with a solid catalyst arranged in a fixed bed; wherein said circulation is implemented at a throughput of between 0.1 and 100 l/h per g of said catalyst.
Claim 2
Independent Claim
75 words
A method of conducting chemical reactions in polyphase systems, comprising the steps of: emulsifying liquid components, which consist of at least two partially or totally immiscible liquids, with an ultrasound emitter or a turbine; continuously circulating said emulsified liquid components; and directly contacting said emulsified liquid components with a solid catalyst arranged in a fixed bed; wherein said circulation is implemented at a throughput of between 0.1 and 100 l/h per g of said catalyst.
Claim 3
Dependent Claim
23 words
The method of claim 1, wherein the step of emulsification with said ultrasound emitter is conducted at a frequency of between 5-500 KHz.
Claim 4
Dependent Claim
23 words
The method of claim 1, wherein the step of emulsification with a turbine is conducted at a rotational speed of between 2000-25,000 r.p.m.
Claim 5
Dependent Claim
26 words
The method of claim 1, wherein the step of emulsification with said ultrasound emitter is implemented when said ultrasound emitter is disposed in said liquid components.
Claim 6
Dependent Claim
32 words
The method of claim 1, wherein the step of emulsification with said ultrasound emitter is implemented when said ultrasound emitter acts through a wall which is in contact with said liquid components.
