Abstract

The invention relates to a new product enabling deodorisation by reducing the content of volatile organic compounds, other than ethylene, which are present in various premises and enclosed areas. The product consists of three elements: - a permanganate which catalytically oxidises the volatile compounds to odourless residues; - a carrier which does not adsorb water, either inert towards the volatile substances (ex. perlite) or adsorbing some of these substances (ex. infusorial earth) - a hygroscopic salt which maintains in the product a moisture level compatible with the oxidation reaction. m

Description

PRODUIT PERMETTANT LA DESODORISATION
DE DIVERS LOCAUX ET ENCEINTES
L'invention concerne un produit réalisant l'absorption et la degradc tion de substances organiques volatiles présentes dans une atmosphère. Elle permet la destruction des odeurs. Ce produit'inorganique, non inflammable, simple, de bas prix de revient et à large spectre d'action est défini dans la présente invention.
PRODUCT ALLOWING DEODORIZATION
VARIOUS PREMISES AND SPEAKERS
The invention relates to a product for absorbing and degrading volatile organic substances present in an atmosphere. It allows the destruction of odors. This inorganic, non-flammable, simple product, of low cost price and with a broad spectrum of action is defined in the present invention.

L'agent transformant les composés volatils est un permanganate fixé sur un support n'absorbant pas l'eau. The agent transforming the volatile compounds is a permanganate fixed on a support which does not absorb water.

Ce support est
- soit inerte vis-à-vis des composes volatils, la seule action du produit étant alors l'oxydation (la perlite par exemple)
- soit adsorbant les produits volatils, l'action étant alors double, adsorption puis oxydation, ce qui augmente l'efficacité du produit (terre d'infusoires : diatomées)
La recherche des meilleures proportions support-permanganate a permi de proposer les valeurs suivantes, support-permanganate de potassium, par exemple, en poids
1/1 dans le cas de supports inertes vis- -vis de l'étnylene
2/1 dans le cas de produits adsorbant l'éthylene.
This support is
- either inert with respect to volatile compounds, the only action of the product then being oxidation (perlite for example)
- either adsorbing volatile products, the action then being double, adsorption then oxidation, which increases the product's efficiency (diatomaceous earth: diatoms)
The search for the best support-permanganate proportions has made it possible to propose the following values, potassium support-permanganate, for example, by weight
1/1 in the case of inert supports against ethylene
2/1 in the case of ethylene-absorbing products.

Une autre originalité de l'invention réside dans le maintien dans le produit d'un taux d'humidité compatible avec la réaction d'oxydation. Ce point est particulièrement important car si aucune précaution n'est prise, le produit se dessèche rapidement et devient inefficace. L'adjonction au produit de sels hygroscopiques tels que le chlorure de calcium permet d'eviter cet inconvénient. A titre d'exemple, une expérimentation portant sur la détermination de la quantité de Ca C12 à ajouter, a montré que les meilleurs résultats étaient obtenus avec des valeurs de
- 0,5 g à 0,75 g pour 1 g de support inerte vis-à-vis de l'éthylène
- 0,5 g à 1 g pour 5 g de support adsorbant l'étnylene.
Another originality of the invention lies in the maintenance in the product of a humidity level compatible with the oxidation reaction. This is particularly important because if no precautions are taken, the product dries out quickly and becomes ineffective. Adding hygroscopic salts such as calcium chloride to the product avoids this drawback. By way of example, an experiment relating to the determination of the quantity of Ca C12 to be added, has shown that the best results are obtained with values of
- 0.5 g to 0.75 g for 1 g of inert support with respect to ethylene
- 0.5 g to 1 g for 5 g of support adsorbing etylene.

Le mode opératoire le plus avantageux consiste à mettre le sel hygroscopique en solution, puis à incorporer cette solution de manière progressive au mélange support-permanganate.  The most advantageous procedure consists in putting the hygroscopic salt in solution, then in gradually incorporating this solution into the support-permanganate mixture.

Les produits obtenus peuvent être, soit utilisés tels quels, soit séchés à une température comprise entre 40 et 600 C. Les produits secs, placés au contact d'air humide se réhydrateront spontanément jusqu'à une teneur en eau compatible avec la réaction d'oxydation. The products obtained can be either used as they are or dried at a temperature between 40 and 600 C. The dry products, placed in contact with humid air will spontaneously rehydrate to a water content compatible with the reaction of oxidation.

Ces produits peuvent être utilisés de plusieurs façons
- lors d'une utilisation statique, le produit placé dans un sac perméable à l'air, fixe les composes volatils traversant le sac
- lors d'une utilisation en circulation d'air, le produit est placé, en vrac ou lité, dans une colonne au travers de laquelle est pulsé l'air charge de composés volatils, ce dispositif permet le traitement de volumes
de gaz beaucoup plus importants.
These products can be used in several ways
- during static use, the product placed in a breathable bag, fixes the volatile compounds passing through the bag
- during use in air circulation, the product is placed, in bulk or in bed, in a column through which the air charged with volatile compounds is pulsed, this device allows the treatment of volumes
much larger gases.

A titre d'exemple, la Figure 1 montre l'efficacité à 25 C de 500 mg de produit réalisé avec le le support adsorbant placé en conditions statiques (sachet de polyester perforé) dans un flacon à plasma de 500 ml dans lequel ont été placés des composés volatils Onconstate que les teneurs en diffé- rents composés choisis parmi les alcools (butanol), les aldéhydes (hexanal) et les esters (acétate d'isoan#le) diminuent rapidement en l'absence de renouvellement d'air. For example, Figure 1 shows the efficiency at 25 C of 500 mg of product produced with the adsorbent support placed under static conditions (perforated polyester sachet) in a 500 ml plasma flask in which were placed volatile compounds Onconstate that the contents of various compounds chosen from alcohols (butanol), aldehydes (hexanal) and esters (isoan acetate) decrease rapidly in the absence of air renewal.

La Figure 2 montre de même l'efficacité de 20g de produit réalise avec le support adsorbant placé en conditions de circulation de I 'atmosphère débit 100 mi par minute -, dans une enceinte de 19 litres. La teneur en hexanal de celle-ci est considérablement diminuée en quelques minutes à 4 C.  Figure 2 similarly shows the effectiveness of 20 g of product produced with the adsorbent support placed under conditions of circulation of the atmosphere flow rate 100 mi per minute -, in a 19-liter enclosure. The hexanal content thereof is considerably reduced in a few minutes at 4 C.

Lors du passage à 250, l'effet obtenu est remarquable puisque la teneur en hexanal augmente considérablement dans l'enceinte témoin, alors qu'elle reste pratiquement identique en présence du produit, démontrant l'action de ce dernier
Les domaines dans lesquels la présente invention peut s'appliquer avec succès sont, par exemple, l'élimination des odeurs dans les locaux à usage d'habitation, de travail ou de transport : odeurs de tabac, émanations de produits chimiques (anhydride sulfureux ...),odeurs de fosse septique, odeurs nausdabondç de putréfaction de la matière vivante (usines de traitements de produits animaux ou végétaux, locaux au voisinage de bassins de fermentation ...)
When passing to 250, the effect obtained is remarkable since the hexanal content increases considerably in the control enclosure, while it remains practically identical in the presence of the product, demonstrating the action of the latter.
The fields in which the present invention can be successfully applied are, for example, the elimination of odors in premises used for living, working or transport: tobacco odors, emanations of chemicals (sulfur dioxide. ..), septic tank odors, nauseating odors of putrefaction of living matter (plants for the treatment of animal or plant products, premises in the vicinity of fermentation tanks ...)
