Abstract
The invention provides an aviation kerosene color developing agent, a color developing method of the aviation kerosene color developing agent and a color developing agent manufacturing method to solve a color developing problem of aviation kerosene. The aviation kerosene color developing agent comprises, by weight, 500 parts of water, 10 parts of sodium carboxymethylcellulose, 250 parts of thin layer chromatography silica gel and 1.5 parts of ethanol.
Description
Technical field
The invention belongs to chemical field, relate to a kind of aviation kerosene developer and coloration method thereof and this developer manufacture method.
Background technology
The aviation kerosene that present China uses is the RP-3 fuel oil, and is because this aviation kerosene outward appearance is as clear as crystal, visual without undissolved water and solid matter.In flight test, whether leak from the fuel tank air hole in order to check in fuel tanker aviation kerosene, require to smear at fuel tank air hole place the chromogenic reagent of aviation kerosene.Yet the aviation kerosene chemical composition is very stable, is difficult to and the reactions such as other materials generation chemistry, colour developing.There is no at present maturation both at home and abroad, can directly apply to the aviation kerosene chromogenic reagent of flight test.The colour developing problem of aviation kerosene is the difficult point that the aircraft fuel tank aerating system is taken a flight test always.
Summary of the invention
Goal of the invention: a kind of aviation kerosene developer and coloration method thereof and this developer manufacture method are provided, solve the colour developing problem of aviation kerosene.
Technical scheme: a kind of aviation kerosene developer comprises: quality is 500 parts of water, 10 parts of sodium carboxymethyl celluloses, 250 parts of tlc silica gels, 1.5 parts of ethanol.
A kind of aviation kerosene developer manufacture method comprises:
Add 10 parts of sodium carboxymethyl celluloses in the water of 500 parts, then ebuillition of heated, fully dissolve sodium carboxymethyl cellulose, until solution becomes transparence, lowered the temperature standing 2 to 5 hours;
Add 250 parts of tlc silica gels;
Add 1.5 parts of ethanol to form the tlc silica gel slurries, stirred 0.5 to 1 hour, until the tlc silica gel slurries mix.
A kind of aviation kerosene coloration method comprises:
Aviation kerosene developer of the present invention is smeared to around tested zone, and 2 to 4 millimeters of thickness dried 6 to 12 hours;
Tested zone with the ultra violet lamp aviation kerosene developer of 254nm is smeared if tested zone shows pale red, shows that there is aviation kerosene in tested zone.
Beneficial effect: whether the present invention can clearly observe aviation kerosene and exist.Under the stationary state of ground, aviation kerosene can keep more than 20 hours on tlc silica gel; Under state of flight, aviation kerosene can keep more than 6 hours on tlc silica gel.The cohesive of the method and aircraft skin is strong, does not come off in flight test.Due to starting material stable chemical natures such as sodium carboxymethyl cellulose, tlc silica gels, the chromogenic reagent of preparation to aircraft skin without any damage.
Description of drawings
Fig. 1 is aviation kerosene coloration method process flow diagram of the present invention.
Embodiment
The aviation kerosene principal ingredient is that carbon atom number is 10～16 saturated alkane, and the content of its aromatic hydrocarbons is not more than the 25%(volume fraction), the content of alkene is not more than the 5%(volume fraction).Arene compound wherein is a kind of compound with conjugated double bond.Under the irradiation of uviol lamp, the π-pi-electron in its conjugated double bond can absorb the energy of uviol lamp, electronic transition occurs, thereby can show color.According to above-mentioned principle, preparation carboxymethylcellulose sodium solution, making tlc silica gel slurries are coated onto tested zone with tlc silica gel, after drying 6 to 12 hours, under the ultra violet lamp of 254nm, can carry out the aviation kerosene chromogenic reaction.Under the irradiation of the uviol lamp of 254nm, aviation kerosene shows pale red.
The invention provides a kind of aviation kerosene developer, comprising: quality is 500 parts of water, 10 parts of sodium carboxymethyl celluloses, 250 parts of tlc silica gels, 1.5 parts of ethanol.
The present invention also provides a kind of aviation kerosene developer manufacture method, comprising:
Add 10 parts of sodium carboxymethyl celluloses in the water of 500 parts, then ebuillition of heated, fully dissolve sodium carboxymethyl cellulose, until solution becomes transparence, lowered the temperature standing 2 to 5 hours; After cooling, undissolved sodium carboxymethyl cellulose meeting sedimentation, get supernatant liquor during preparation.
Add 250 parts of tlc silica gels.
Add 1.5 parts of ethanol to form the tlc silica gel slurries, stirred 0.5 to 1 hour, until the tlc silica gel slurries mix.
The present invention also provides a kind of aviation kerosene coloration method, as shown in Figure 1, comprising:
S101, aviation kerosene developer of the present invention is smeared to around tested zone, 2 to 4 millimeters of thickness dried 6 to 12 hours.
S102, the tested zone of smearing with the ultra violet lamp aviation kerosene developer of 254nm if tested zone shows pale red, show that there is aviation kerosene in tested zone.
