In EP-A documents 0286610 and 0778085 2-hexenylanthraquinone is cited as a reaction carrier along with other 2-alkylanthraquinones and mixtures. Which of the possible hexenyl isomers is meant and whether or which advantages can be achieved therewith can not be gathered from these EP documents. It is known that as the chain length of the alkyl substituent increases in 2-alkylanthraquinones the quinone solubility increases; however, at the same time, and this is probably more important for practicability, the rate of hydrogenation drops off sharply. Thus, it was not obvious to seriously consider the use of a 2-C.sub.6 -alkylanthraquinone as a reaction carriers.
It follows from JP-A 58 180452 and JP-A 59 051235 that 2-(4-methyl-3-pentenyl)-1,4-dihydroanthraquinone as well as 2-(4-methyl-3-pentenyl)anthraquinone obtainable therefrom and 2-(4-methylpentyl)anthraquinone can be used as reaction carriers for the production of hydrogen peroxide. The production of the cited compounds--the parent compound is obtained by Diels-Alder reaction from 1,4-naphthoquinone and myrcene--can be gathered from these documents. Concerning the use of these compounds in the cyclical anthraquinone process for the production of hydrogen peroxide, it is solely mentioned that the same results can be obtained as with known 2-alkylanthraquinones.
The requirements placed on a good reaction carrier are occasionally only partly fulfilled when using a single 2-alkylanthraquinone and/or the corresponding 2-alkyltetrahydroanthraquinone, formed in situ, as a function of the operating conditions. Great efforts were therefore undertaken by those in this field of technology to improve the reaction carrier by using at least two different 2-alkylanthraquinones and/or their tetrahydro derivatives. However, advantages regarding the one or the other requirement on a good system of reaction carriers often oppose disadvantages regarding other criteria.

It is known that as the range length of the alkyl substituent increases in 2 - alkylanthraquinones the quinone solubility increases; however, at the like time, and this is probably more authoritative for practicability, the rate of hydrogenation drops off aggressively. Thus, it was not obvious to seriously consider the manipulation of a 2 - C.sub.6 -alkylanthraquinone as a reaction carriers. 
 It follows from JP - A 58 180452 and JP - A 59 051235 that 2-(4 - methyl-3 - pentenyl)-1,4 - dihydroanthraquinone equally well as 2-(4 - methyl-3 - pentenyl)anthraquinone obtainable therefrom and 2-(4 - methylpentyl)anthraquinone can be use as reaction carriers for the production of hydrogen hydrogen peroxide. The production of the cited compounds -- the parent compound is obtained by Diels - Alder reaction from 1,4 - naphthoquinone and myrcene -- can be gathered from these document. Concerning the use of these compounds in the cyclical anthraquinone process for the production of hydrogen peroxide, it is solely mentioned that the same consequence can be obtained as with known 2 - alkylanthraquinones. 
 The prerequisite placed on a good reaction carrier are occasionally merely partly fulfilled when using a single 2 - alkylanthraquinone and/or the comparable 2 - alkyltetrahydroanthraquinone, formed in situ, as a function of the operating conditions. Great efforts were therefore undertaken by those in this field of technology to improve the reaction carrier by use at least two unlike 2 - alkylanthraquinones and/or their tetrahydro derivative instrument. However, advantages regarding the one or the other requirement on a effective system of reaction carriers frequently oppose disadvantages regarding other criterion.
