preparation Embodiment 1

[0028] Preparation of Polymer 1

[0029] Polymer 1 is a linear polyisoprene containing coumarin groups. That is, the polymer template of polymer 1 is linear polyisoprene, and the labeling group is a fluorescent coumarin group. The structure is shown in the following formula, and the linking method adopted is "click" chemistry.

[0030]

[0031] The specific reaction steps of the experiment are as follows:

[0032] (1) Preparation of linear polyisoprene (L-PB)

[0033] The isoprene that has been pre-removed by n-BuLi is vaporized and introduced into cyclohexane to form a cyclohexane solution of isoprene (monomer:solvent=1:8, w / w=1: 8), and then introduce 100ml of cyclohexane solution into the polymerization bottle that has been evacuated-baked-argoned three times with high-purity argon, and then placed in a 50°C constant temperature water bath to preheat for 10min. Add 0.4ml of n-BuLi to kill impurities in the bottle, then quickly add 5.1ml of n-BuLi to initiate the polym...

Embodiment 2

[0051] Preparation of Polymer 2

[0052] Polymer 2 is a four-armed star polyisoprene containing coumarin groups

[0053] Reactive polyisoprene PI-Li in the preparation of repeated polymer 1 + Synthetic steps of , first add metered SiCl after reacting for 3h 4 (nSiCl 4 / nLi=1 / 4), coupled at 50° C. for 4 h, adding the terminator isobutanol, coagulated with ethanol to sink the gel, and dried in a vacuum oven to constant weight. A series of steps of epoxidation-ring-opening-bromination-azidation-"click" chemical reaction in the preparation process of polymer 1 was repeated to synthesize four-armed star polyisoprene containing coumarin groups. GPC characterization results are as follows, M w =8800, M w / M n =1.04,f w = 4, f w represents the number of polymer arms.

Embodiment 3

[0055] Preparation of Polymer 3

[0056] Polymer 3 is a comb polyisoprene containing coumarin groups.

[0057] Linear comb polyisoprene is obtained by coupling active polyisoprene chains with refined linear polyisoprene epoxy coupling agent. Repeat the synthesis steps of active polyisoprene in the preparation of polymer 1, add a refined solution of known concentration, couple at 50°C for 4 hours, and dry the sample in a vacuum oven to constant weight to obtain linear branched polyisoprene The crude product of alkenes was fractionated by precipitation to remove uncoupled oligomers. A series of steps of epoxidation-ring-opening-bromination-azidation-"click" chemical reaction in the preparation process of polymer 1 was repeated to synthesize star-shaped comb polyisoprene containing coumarin groups. GPC characterization results are as follows, Mw=7000, Mw / Mn=1.05, fw=4.

Abstract

The invention relates to an oil marker, and in particular relates to an oil mark polymer and a preparation method and application thereof. The oil mark polymer is formed by connecting one or more oil identification groups with a polymer template through a chemical bond, wherein the polymer template is a polymer with a three-dimensional topological structure obtained by homo-polymerizing or copolymerizing olefin monomer or a polymer additive in the refined oil product; the identification group is one or more of colored groups, fluorescence groups and near infrared groups. A light-emitting group in the oil mark polymer provided by the invention has the advantages of aggregating and enhancing, and the usage amount of identification small molecule is reduced; the marker is hard to reject by use of a molecular sieve and other traditional means; a chromophoric group has a certain degree of red shift / blue shift, so that a novel chromatographic peal identification is produced, and the anti-fake level is increased.

Description

technical field [0001] The invention relates to an oil marker, in particular to an oil marker polymer, a preparation method and an application. Background technique [0002] Oil product marking refers to the filling and management plan of adding marked compounds to oil products and supporting corresponding markers, and identifying oil products through physical or chemical detection of marked oil products. The scope of application of oil product marks mainly includes financial marks and corporate brand marks. Fiscal marks are mainly related to the taxation of oil products by government departments. The government uses markers to ensure reasonable taxation of special fuels; while corporate brand marks are mainly related to anti-counterfeiting of oil products in petrochemical companies. These large companies often spend huge financial resources to ensure their brands. The performance indicators of the oil, such as volatility or octane number, thus protecting its products from ...
