Abstract
The present invention relates to a polymer material with action of removing thioalcohol. It can be used for removing thioalcohol in gas or liquid organic material. It is characterized by that said polymer material contains positive dibasic copper ions, said copper ions can be connected on the polymer skeleton by means of chelation group.
Description
Technical field
The present invention relates to composition, refer in particular to the polymer materials with dethiol action, it can be used in the gas or the removing of mercaptan in the liquid state organics.
Background technology
Mercaptan has stench, as long as contain few low-carbon (LC) mercaptan in gas or the liquid state organics, will have undesirable stink.Mercaptan is again to have highly active organism, and the existence of mercaptan can have a strong impact on the use properties of organic chemical industry's product, and the stability of gasoline, diesel etc. and storage stability are descended, also can corroding metal, shorten the work-ing life of equipment.Remove mercaptan and be not only the needs that guarantee quality product; also be the protection environment, improve one of effective measure of Air quality; this is particularly important for the great gasoline of daily consumption, diesel oil, Sweet natural gas etc., and is also significant for many industries such as chemical industry, material, pharmacy and thermoelectricity.
The traditional method that removes mercaptan is alkali cleaning, promptly allows the material that contains mercaptan fully contact with certain density alkali lye, removes mercaptan.But owing to there are problems such as waste lye pollution and corrodibility, alkali wash is not an ideal mercaptan removal method.Other method that removes mercaptan mainly is a catalytic oxidation, promptly under certain catalytic condition, remove mercaptan by oxidizing reaction, concrete technology comprises liquid-liquid method, liquid-solid method, and carried by active carbon phthalocyanine cobalt is the no caustic alkali fixed bed process of catalyzer, the improvement fixed bed process (CN1067709C) that activated carbon fiber is carried cobalt, copper or zinc salt, the main drawback of these technologies is on the one hand need be with highly basic or comparatively expensive material as catalyzer, need aerating oxygen or air as oxygenant on the other hand, cost is higher, and technology is also complicated.
Summary of the invention
The present invention proposes a kind of polymer materials that removes the mercaptan effect that has, this material is used for gas or liquid state organics material mercaptan removal, can make that mercaptans content obviously reduces in the material.Do not need highly basic or other catalyzer in the mercaptan removal process, also need not use air or oxygen, easy to use, suitability is wide.
This polymer materials is the chelating type polymkeric substance that combines positive bivalent cupric ion, and outward appearance is fibrous or particulate solid, makes according to the ordinary method reaction with polymkeric substance that has chelation group and cupric salt.
The technical scheme that realizes above-mentioned purpose is as follows:
It is of the present invention that to have the polymer materials that removes the mercaptan effect be the chelating type polymkeric substance that combines bivalent cupric ion, it is characterized in that polymer materials contains the cupric ion of positive divalence, cupric ion is connected on the polymer backbone by chelate group, and the structural table of this polymer materials is shown:
In the following formula
Be the chelating type polymkeric substance, wherein
The expression polymer backbone,
ChExpression is used for and cupric ion bonded chelate group.
Skeleton in this polymer materials

In this polymer materials with cupric ion bonded chelate group
ChComprise phosphonic acids, aminophosphonic acid, aminocarboxylic acid, amido thiocarboxylic acid, together with hydroxamamide, thiocarbamide and amido thiocarbamide.
Of the present invention have the polymer materials that removes the mercaptan effect and obtained by corresponding chelating polymer and copper salt solution reaction, and used mantoquita is positive bivalent cupric ion and the compound of negatively charged ion formation.Content of copper ion is between 0.5-10mmol/g in the polymer materials that makes.
Its using method is to separate after making the gas that contains mercaptan or liquid state organics and polymer materials contact certain hour of the present invention, and original mercaptan can significantly reduce or all disappears in isolated gas or the liquid state organics.
Beneficial effect of the present invention is as follows:
(1) polymer materials of the present invention has the effect that significantly removes for the mercaptan that contains in gas or the liquid state organics.Decreasing ratio to mercaptan under the experiment condition reaches 25-90%.
When (2) polymer materials of the present invention is used for removing the mercaptan of material, do not need aerating oxygen or air, do not need the highly basic condition yet, safe.
(3) this polymer materials can be regenerated according to ordinary method, reuses.
