The main purpose of the present invention is to provide a kind of decolorizer of geranyl butyrate and decolorization method thereof, effectively reduce chromaticity, thereby be more suitable for practical use, and have industrial utilization value.
The purpose of the present invention and the solution to its technical problems are achieved by adopting the following technical solutions. According to the decolorizing agent of a kind of geranyl butyrate that the present invention proposes, described decolorizing agent is the activated carbon that is loaded with 1～20% ZnO, and described loading is in mass percent.
Further, the decolorizing agent of the aforementioned geranyl butyrate, the decolorizing agent is activated carbon loaded with 1 ~ 10% ZnO, the loading is in mass percentage, most preferably is the activated carbon loaded with 5% ZnO Activated carbon.
The decolorization method of geranyl butyrate comprises the following steps,
(1) put the decolorizer into the fixed bed for pretreatment,
(2) Heating geranyl butyrate, passing it into a fixed bed equipped with a decolorizing agent for decolorization, and obtaining the target product after filtering.
Further, in the decolorization method of the aforementioned geranyl butyrate, during the pretreatment of the decolorizing agent in (1), the fixed bed heating temperature is 300 ~ 500 ° C, while passing through hydrogen for 3 ~ 6 hours, then the The fixed bed is kept warm at 80-150°C.
Further, the decolorization method of aforementioned geranyl butyrate, the heating temperature of geranyl butyrate in the described (2) is 80～150 ℃, when geranyl butyrate is passed into fixed bed, stop passing into the hydrogen.
Further, the decolouring method of aforementioned geranyl butyrate, the weight flow velocity that described geranyl butyrate passes into fixed bed is 1～2kg geranyl butyrate/kg decolorizing agent hour.
By means of the above-mentioned technical scheme, the decolorizing agent of geranyl butyrate and the decolorizing method thereof of the present invention have at least the following advantages.
The preparation method of the decolorizing agent adopted in the present invention is simple, and can be obtained by impregnation or other loading methods. The decolorizing agent is non-toxic and harmless, and can prepare geranyl butyrate with low chroma, and after the decolorizing agent is treated with hydrogen, Has chemical reduction, can consume dissolved oxygen in geranyl butyrate, is not conducive to the survival of microorganisms, can make the product have a longer-lasting fresh fragrance and a longer shelf life, and the decolorization method of geranyl butyrate of the present invention, the overall The operation process is relatively simple, and low-color geranyl butyrate can be quickly produced, which is suitable for the production of daily cosmetic essence, soap and food essence, and meets various production needs.
