Description
Technical field
The invention belongs to petrochemical industry, in particular to a kind of preparation method of agriculture refined mineral oil.
Background technique
Mineral oil pesticide belongs to petroleum-type mineral source pesticide in pesticide classification, and main component is mineral oil.Medicine oil principle
It is that medicament forms one layer of oil film on polypide, chorion, mycelia or weeds surface after sprinkling, sealed porosity leads to its death by suffocation
It dies, belongs to physical killing effect.Medicament oxidation-degradable under illumination condition, thus residual life is short, to people and animals, Environmental security without
Evil is that a kind of ideal pest persistently controls pesticide control.
Mineral oil pesticides application is extensive, has commercialization series of products and on the country such as the U.S. and Asia, South America and ground
Area uses, and is widely used in the anti-of the various pests such as agricultural scale insect, aphid, acarid in fields such as vegetables, fruit tree, gardening flowers and plants
It controls.The U.S. is earliest to the research of mineral oil pesticide, most widely used, and every annual consumption of California mineral oil pesticide is up to 10000 tons.
It is mainly used for citrus, apple, the prevention and control of plant diseases, pest control on deciduous fruit tree and nut and vegetables；In Italy, mineral oil pesticide is used
On citrus since 1940, current usage amount is 7000 tons, accounts for the 12% of citrus dosage.And the present usage amount in China
Only 7000-8000 tons, not as good as the 1% of U.S.'s dosage.
Although China's mineral oil pesticide has very long usage history, but without special agricultural mineral oil base in some time
Plinth oil standard, basic oil quality are irregular.Beginning International Petroleum Price is substantially increased suddenly within 2005, some mineral oil pesticides
Enterprise largely uses base oil inferior, and phytotoxicity phenomenon is caused frequently to occur, for this purpose, the Ministry of Agriculture in 2008 has promulgated No. 1133 public affairs
It accuses, it is specified that manufacturing enterprise should select refined mineral oil and ordinary petroleum products must not be used to produce mineral oil pesticide, and define
The opposite n-alkane carbon number difference of refined mineral oil is not more than 8, opposite n-alkane average carbon number between 21-24, non-sulfonated
Object content is not less than 92%.
Up to the present, domestic that the refined mineral oil for meeting No. 1133 bulletin of the Ministry of Agriculture, agriculture are produced there are no enterprise
Medicine manufacturing enterprise can only rely on import.
Summary of the invention
It is an object of the invention to provide a kind of preparation method of agriculture refined mineral oil, the method can fill up the agricultural essence in China
Refine the autonomous production blank of mineral oil.
The object of the invention can be realized so that the following technical solution is employed:
A kind of preparation method of agriculture refined mineral oil, comprising the following steps:
(1) hydroisomerizing 2cst base oil is subjected to true boiling point distillation as raw material and cuts fraction；
(2) using temperature range in 330-390 DEG C of fraction as product.
Cst (dynamic viscosity) refers to the measurement of internal friction when liquid flows under the effect of gravity, and value is identical
At a temperature of liquid dynamic viscosity and the ratio between its density, unit is mm2/s。
The purpose for cutting fraction is to select the fraction range for meeting refined mineral oil index of correlation.
Preferably, the pressure of step (2) distillation is 1310Pa-1350Pa；Theoretical cam curve is 14；Reflux ratio is 5:1.
It has been found that preferable using above-mentioned parameter effect when true boiling point distillation.
The purpose of hydroisomerizing is under the action of catalyst, and macromolecular n-alkane isocraking is identical at molecular weight
Or smaller isoparaffin, so that reaching reduces the pour point of oil product, improves viscosity and yield.
Preferably, the carbon number distribution of 10%~90% fraction of product is 21-24；Pour point≤- 20 DEG C；Kinematic viscosity (40 DEG C)
For 9.0~13.0mm2/s；Unsulfonated residue >=96%；Sulfur content≤10mg/kg.
The present invention carries out true boiling point distillation and fraction cutting using the 2cst base oil by hydroisomerizing as raw material, cuts
The conduct product for meeting index request is chosen after cutting.The present invention realizes the production domesticization of agricultural refined mineral oil, can therefore mention
The added value of high refined oil product, to obtain better economic benefit.
Specific embodiment
The present invention is further explained in the light of specific embodiments, so that those skilled in the art can preferably manage
The solution present invention can be simultaneously practiced, but illustrated embodiment is not as a limitation of the invention.
Used hydroisomerizing 2cst base oil is produced by China Petroleum & Chemical Co., Ltd. Maoming Branch；This
Distilling apparatus used in inventing is that the FY type of China Petroleum & Chemical Corporation Research Institute of Petroleum production is former
Oily true boiling point distillation experimental rig.
True boiling point distillation condition of the invention are as follows: 14 pieces of theoretical cam curve, reflux ratio 5:1, operating pressure 1310Pa-
1350Pa is preferably kept in 1330pa.
Performance evaluation is carried out to raw material of the present invention, as a result as follows:
The performance indicator of 1 hydroisomerizing 2cst base oil of table
The research of one fraction physicochemical property of embodiment
Narrow fraction is carried out to the 2cst base oil of hydroisomerizing device production under the foregoing conditions and distills cutting test, cutting
330 DEG C out~390 DEG C fractions, investigate its performance, are shown in Table 2.
330~390 DEG C of ends fraction physicochemical properties of 2 2cst base oil of table
As seen from Table 2,330~390 DEG C of fraction narrow fractions have 100% saturated hydrocarbons, zero aromatic hydrocarbons, the very low spy of sulfur content
Point, the carbon number distribution of 10%~90% fraction only have 3, and the average carbon number of 50% fraction is 22.6, complies fully with pesticide ring
Guarantor's type mineral base oil index request.
Two mass spectrum composition analysis of embodiment
It send Research Institute of Petro-Chemical Engineering, Fushun Petrochemical Research Institute to be analyzed by mass spectrometry in sample, is shown in Table 3.
3 mass spectrum composition analysis of table
| Shi Ke institute test result | Fu Yan institute test result | |
| Alkane, % | 62.9 | 65.5 |
| Total cycloalkane, % | 35.9 | 33.2 |
| Mononuclear aromatics, % | 1.2 | 1.3 |
| Total aromatic hydrocarbons, % | 1.2 | 1.3 |
As seen from Table 3, aromatic hydrocarbons does not have fully saturated in oil product after hydroisomerizing dewaxing technique, still contains 1.2%
~1.3% aromatic hydrocarbons.
Three refined mineral oil index analysis of embodiment
Agriculture chemical examination institution, Hebei province is sent to carry out, opposite poor (the i.e. carbon number of 10%~90% fraction of n-alkane carbon number range
Distribution), opposite n-alkane average carbon number (i.e. the average carbon number of 50% fraction) test, the results are shown in Table 4.
| Detection project | Quality index | Actual numerical value |
| Opposite n-alkane average carbon number | 21~24 | 21 |
| Opposite n-alkane carbon number range is poor ,≤ | 8 | 3 |
| Unsulfonated material content, vol%, >= | 95 | 98.0 |
As seen from Table 4, the measurement of agriculture chemical examination institution, Hebei province shows the non-sulfonated object content, relatively just of product of the invention
Structure alkane carbon number range differences and the performance of opposite n-alkane average carbon number comply fully with " No. 1133 text of the Ministry of Agriculture " pesticide use
The index request of environment-friendly type mineral base oil.
It is not limiting the scope of the present invention with the above embodiment of the present invention, embodiments of the present invention are unlimited
In this, all this kind above content according to the present invention is not being departed from according to the ordinary technical knowledge and customary means of this field
