Abstract
Abstract The invention relates to a process for the vaporization of volatile active compounds and mixtures of active compounds according to which the active compound or the mixture of active compounds is conveyed from its storage vessel by the use of an electrolytically produced gas stream into the room which is to be supplied with a vaporizing mixture of active compounds, and is there caused to vaporize directly or by the use of inert vaporizers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
86 words
A process for the linear continuous vaporization of volatile active compounds and mixtures of active compounds, which process comprises continuously conveying the active compound of the mixture of active compounds from a storage vessel containing the active compound or mixture of active compound by means of an electrolytically produced gas into a room which is to be supplied with a vaporizing active compound, and allowing the active compound or mixture of active compounds to vaporize in said room directly or by means of an inert vaporizer.
Claim 2
Dependent Claim
86 words
A process for the linear continuous vaporization of volatile active compounds and mixtures of active compounds, which process comprises continuously conveying the active compound of the mixture of active compounds from a storage vessel containing the active compound or mixture of active compound by means of an electrolytically produced gas into a room which is to be supplied with a vaporizing active compound, and allowing the active compound or mixture of active compounds to vaporize in said room directly or by means of an inert vaporizer.
Claim 3
Dependent Claim
13 words
The process of claim 1, wherein the gas produced electrolytically is oxyhydrogen gas.
Claim 4
Dependent Claim
19 words
The process of claim 1, wherein the active compound or the mixture of active compounds is a perfume oil.
Claim 5
Dependent Claim
41 words
The process of claim 1, wherein the active compound or mixture of active compounds conveyed from the storage vessel into the room to be applied with a vaporizing active compound is distributed within the room by means of an inert vaporizer.
Claim 6
Dependent Claim
31 words
A device for carrying out the process according to claim 1, comprising an electrolytic cell and a storage vessel for the active compound or mixture of active compounds to be vaporized.
Claim 7
Dependent Claim
88 words
The device of claim 5, wherein the electrolytic cell contains two electrodes and water which has been acidified with sulfuric acid, and the oxyhydrogen gas evolved in the electrolysis is introduced via a line into the storage vessel and there exerts pressure on the surface of the active compound or mixture of active compounds of the solution of active compound to be vaporized and conveys the active compound through an exit line into the room to be supplied with the vaporizing active compound or mixture of active compounds.
