Description
Technical field
The present invention relates to a kind of heat-conduction medium, be specifically related to a kind of heat that can use in anhydrous and oxygen-free reaction temperature control operating mode
Transmitting medium.
Background technology
Many special compounds, to water or oxygen sensitive, are met water or chance oxygen can be occurred vigorous reaction；In order to study
The synthesis of this compounds, separation, purification and Analysis and Identification, it is necessary to use special instrument and anhydrous and oxygen-free operating technology.No
Then, even if synthetic route and reaction condition are all suitable, the most also can not get intended product.So, anhydrous and oxygen-free operates
The utilization that technology is wide in organic chemistry and inorganic chemistry.
In the middle of daily Chemical Manufacture, needing to use anhydrous and oxygen-free reaction in part chemosynthesis, this kind of reaction is general all
It it is very exothermic reaction.At present, this kind of chemosynthesis controls temperature typically refrigeration and heating two parts, and refrigerating part is generally adopted
With saline or ethylene glycol as the semi-open type refrigeration system of refrigerant, and heating part generally uses steam as adding thermal medium
Heating system, refrigerant and add thermal medium both media be both needed to enter reacting kettle jacketing, carry out drop mild heat mutual
Switching.But, saline and ethylene glycol solution all contain hydroxyl, chloride ion, moisture, oxygen isoreactivity material, once and anhydrous and oxygen-free
Reaction mass contacts, and just explodes, there is the biggest potential safety hazard；And saline and ethylene glycol solution have stronger metal erosion
Property, life-time service, greatly reduce service life of equipment；Saline is relatively strong because of corrosivity, is typically used as the cryogenic heat transfer of-40～20 DEG C
Medium, ethylene glycol solution is typically used as-20～80 DEG C of temperature ranges, uses temperature range to receive considerable restraint.
Summary of the invention
It is an object of the invention to provide a kind of heat-conduction medium, in order to control the temperature in anhydrous and oxygen-free reaction operating mode.
In order to realize foregoing invention purpose, the technical scheme is that
A kind of heat-conduction medium, it is characterised in that include following component:
With alkylaromatic hydrocarbon class and, raw material based on high-pressure hydrogenation alkanes substance, add high temperature anti-coking agent and hydrogenation scale inhibition
Agent.
Further, being in terms of 100% by heat-conduction medium gross weight, the content of each component is as follows；Alkylaromatic hydrocarbon class material 5%
～90%, high-pressure hydrogenation alkanes substance 7%～92%, high temperature anti-coking agent 1%～2%, it is hydrogenated with antisludging agent 1%～2%.Enter one
Step, described alkylaromatic hydrocarbon class material is alkylbenzene.
Further, described alkylbenzene aromatic hydrocarbon substance is selected from detergent alkylate, propylbenzene and the one of a diethylbenzene
Or it is multiple.
Further, described alkanes base oil is hydrogenation alkanes base oil.
Further, described hydrogenation alkanes base oil is low sulfur and low aromatics special type oil..
Further, described alkylbenzene is detergent alkylate, propylbenzene and a diethylbenzene.
Further, being in terms of 100% by heat-conduction medium gross weight, each constituent content of alkylbenzene is: detergent alkylate 10%,
Propylbenzene 50%, a diethylbenzene 20%.
Further, described alkylbenzene is detergent alkylate and propylbenzene, is in terms of 100% by heat-conduction medium gross weight, alkane
The each constituent content of base benzene is: detergent alkylate 85%, propylbenzene 5%.
Further, described alkylbenzene be between diethylbenzene, be in terms of 100% by heat-conduction medium gross weight, a diethylbenzene
Content is 5%.
The Novel hot transmitting medium that the present invention provides, has saturated hydrocarbons characteristic, the most aqueous, oxygen and other active group things
Matter, and there is not any reaction in anhydrous and oxygen-free reaction mass, protects oxygen-free environment, exempt the potential safety hazard therefore brought；And this
Product is corrosion-free to metal, low toxicity, environmental protection；And this product can meet-80～300 DEG C of different temperatures want according to different ratio
Operating mode is asked to use；Same medium can be used, it is to avoid cooling and adding in anhydrous and oxygen-free reaction temperature control (fall mild heat) operating mode
Heat uses different medium, does not results in because handover operation brings medium to waste.
