Problems solved by technology

But adopt the white oil product that this preparation method obtains, naphthenic characteristic is stronger, the paraffin content that distillate oil hydrocarbons forms is too low, and naphthene content is then relatively high, so the absorption when being used to prepare poultry vaccine will be reduced Poor, prone to inflammatory reactions

Embodiment 1

[0049] The atmospheric and vacuum fraction of paraffin-based crude oil and the atmospheric and vacuum fraction of naphthenic crude oil are blended into a mixed fraction according to the mass ratio of 85:15. Atmospheric and vacuum distillate of alkyl crude oil cuts 280~360℃ distillate oil. The mixed fraction in this example is recorded as feed oil 1, and the specific properties of feed oil 1 are shown in Table 1.

[0050] The raw material oil 1 is subjected to hydrogenation pre-refining, so that the hydrogenation pre-refining product meets the limited requirements of the high-pressure hydrogenation process for feed oil: the total metal content is less than 2.0 μg / g, the content of n-heptane insolubles is less than 0.02%, and the salt content The iron content is less than 1.0mg / L, the water content is less than 300μg / g, the iron content is less than 1.5μg / g, and the carbon residue is less than 1%.

[0051] Under the hydrogen partial pressure of 17MPa, the hydrorefined products ...

Embodiment 2

[0058] This embodiment provides a preparation method of white oil for poultry vaccine injection. The raw material oil and catalyst used are the same as in Example 1. First, the mixed fraction (i.e. raw material oil 1) is hydrogenated and pre-refined to make the hydrogenated pre-refined product Reach the limit requirements of high-pressure hydrogenation process for feed oil; then carry out three-stage high-pressure hydrogenation reaction under the hydrogen partial pressure of 18MPa, in which:

[0059] Hydrotreating: reaction temperature is 380°C, space velocity is 1.0h -1 , The volume ratio of hydrogen to oil is 1500:1;

[0060] Isomerism depreciation: reaction temperature is 350°C, space velocity is 0.5h -1 , The volume ratio of hydrogen to oil is 1500:1;

[0061] Supplementary hydrogenation refining: reaction temperature 300°C, space velocity 2.2h -1 , The volume ratio of hydrogen to oil is 2000:1.

[0062] The reaction product obtained from the three-stage high-pressure ...

Embodiment 3

[0064] Atmospheric and vacuum distillates of paraffinic crude oil and atmospheric and vacuum distillates of naphthenic crude oil are blended into mixed fractions according to the mass ratio of 70:30. Atmospheric and vacuum distillate of alkyl crude oil cuts 300-380°C distillate oil. The mixed fraction in this example is recorded as feed oil 2, and the specific properties of feed oil 2 are shown in Table 1.

[0065] Hydrogenation and pre-refining of raw oil 2, so that the hydro-pre-refining product meets the limit requirements of high-pressure hydrogenation process for feed oil: the total metal content is less than 2.0 μg / g, the content of n-heptane insolubles is less than 0.02%, and the salt content The iron content is less than 1.0mg / L, the water content is less than 300μg / g, the iron content is less than 1.5μg / g, and the carbon residue is less than 1%.

Abstract

The invention provides white oil for poultry vaccine injection and a preparation method thereof, and relates to the technical field of vaccine oil. Wherein, the preparation method of the white oil for poultry vaccine injection comprises: mixing the atmospheric and vacuum distillate oil of paraffin-based crude oil and the atmospheric and vacuum distillate oil of naphthenic crude oil to obtain a mixed distillate; performing hydrogenation pre-refining on the mixed distillate , and under a hydrogen partial pressure of 15.0-20.0 MPa, the hydrogenation pre-refined product is sequentially subjected to hydrogenation treatment, isomerization decondensation and hydrogenation supplementary refining; take the 290-370 ° C fraction of the hydrogenation supplementary refined product to obtain poultry White oil for vaccine injection. The white oil for poultry vaccine injection provided by the invention has the characteristics of good poultry body absorption and high antibody titer, and is odorless, tasteless, and aromatic-free, and has excellent color stability and antioxidant stability.

Description

technical field [0001] The invention relates to the technical field of vaccine oil, in particular to a white oil for poultry vaccine injection and a preparation method thereof. Background technique [0002] White oil is a special mineral oil obtained through deep refining to remove impurities such as sulfur, nitrogen, oxygen and aromatics. White oil is a hydrocarbon compound, except for extremely small impurities, it is composed of two elements, carbon and hydrogen, and is generally composed of paraffins and naphthenes. In terms of composition and structure, it can be further divided into paraffinic white oil and naphthenic white oil. Among them, the content of paraffins in the paraffinic white oil is relatively high, while the content of naphthenes in the naphthenic white oil is relatively high. White oil is colorless, tasteless, odorless, non-corrosive and chemically inert, and is widely used in daily chemical industry, pharmaceutical production, food processing, instrum...
