Definitions
- the invention relates to highly oxidized rice bran wax oxidates, in particular
- Montanwachs can be with the help of these chromic acid-based process and renewable natural waxes such.
- carnauba wax, candelilla wax, etc. oxidize.
- a process for chromic acid oxidation of carnauba wax has been described, for example, in DE-10231886.
- Natural carnauba waxes fat gray, type 4, medium yellow, primagelb and flor, types 3 to 1 and in particular raw montan wax (black) are markedly dark. The oxidation with chromosulfuric acid leads to much brighter to white
- the chromic acid bleaching of said natural waxes leads to high and defined acid numbers (typically: 130 to 160 mg KOH / g).
- acid numbers typically: 130 to 160 mg KOH / g.
- the level of acidity is a measure of the free waxy acid content.
- the typical conversions of such Oxidatiohen are in the range of about 50 to 90% with respect to the ester groups.
- the thus bleached natural waxes therefore have, in addition to the desired lightening, a higher saponification number and acid number, which are associated with additional advantageous processing properties.
- the recovered acid waxes are eminently suitable for use therefrom e.g. by esterification with
- CONFIRMATION COPY mono- or polyvalent alcohols such as methyl alcohol
- Wax raw materials a variety of so-called semi-synthetic waxes accessible, which can be tailored to the particular application requirements specifically optimally. Naturally, the potential for adaptation by esterification, saponification etc. is greater, the higher the content of free acids in the primary oxidation product is set.
- the chromic acid oxidation of rice bran wax (hereinafter rice wax) is different than in the case of the abovementioned natural waxes, even with stoichiometric to superstoichiometric chromic acid with only low conversions of the ester groups. It essentially comes only to a whitening of rice wax.
- the patent application JP-36005526 describes the preparation of solvent-containing polymer compositions in which a chemically modified wax based on rice wax is contained. The modification takes place by oxidation of crude rice wax with chromium trioxide or chromic acid salts in the presence of sulfuric acid and, if appropriate, subsequent esterification and / or
- lipid components which are predominantly made up of fatty oils and, to a lesser extent, waxy components.
- the latter can be found in the obtained from the bran by pressing or solvent extraction oil, from which they are due to their poor solubility at low temperatures, for. B. isolated by freezing.
- Rice wax is according to the Journal of Scientific and Industrial Research, 2005, Vol. 64, 866-882, one would use the entire world rice production in addition to rice oil also to win the rice wax, at about 300,000 tons per year.
- Rice wax belongs to Ullmann's Encyclopedia of Industrial Chemistry, 5 fh ed.

- the composition of the wax body is made of wax esters.
- the rice bran wax esters mainly consist of
- Monoesters of long-chain saturated unbranched fatty acids with long-chain unbranched aliphatic alcohols are predominantly in the acid moiety behenic, and lignoceric acid with chain length C22 and C24 and in the

- Other variable constituents of the rice bran wax to be regarded as minor components are the unspecified "dark substances", squalene and the so-called "gum" fraction. These usually lead to a fluctuating in color and applicability and difficult to reproduce product quality.
- the object of the invention is therefore to provide rice wax oxidates having defined properties and constantly high acid numbers as a raw material for chemical derivatizations. This creates the opportunity to meet the technical needs of different applications in an optimally adapted way. Contrary to the prior art, it has now surprisingly been found that the chromic acid oxidation of rice wax leads to high conversions in terms of the esters and thus to high acid numbers, preferably> 100 mg KOH / g, if the rice wax has previously been dried under harsh alkaline conditions (220 ° C.). 12 bar) was hydrolyzed.
- the invention relates to rice bran wax oxidates having an acid number measured in accordance with DIN ISO 2114 greater than 70 mg KOH / g, preferably greater than 100 mg KOH / g, more preferably greater than 140 mg KOH / g.

- the characteristic weight ratio of behenic acid to melissic acid C 22 : C 3 o is in the inventive
- Rice bran wax oxidates between 1.0: 0.8 to 1: 1.2, preferably between 1.0: 0.8 to 1.0: 1.05.

- the saponification number measured according to DIN ISO 3681, increases by at least 50%, preferably by at least 80%, particularly preferably by at least 150%, as a result of the oxidation of the rice bran growth raw material.

- Saponification number is also a measure of the actually occurring oxidation in contrast to saponification, in which the saponification number is known not to change, and in contrast to other bleaching processes in which there is only a whitening of the product. For example, whitening rice bran wax with hydrogen peroxide does not cause chemical modification of the rice bran
