Embodiment 1

[0027] An embodiment of the present invention provides a method for detecting the quality of a candle, which uses vanillin to detect iron in the candle. Specifically, the method includes:

[0028] Heat and melt the candle that may contain iron or the candle to be tested into wax liquid;

[0029] Slowly add the hydrochloric acid solution into the wax liquid, stir evenly, and react;

[0030] After the reaction finishes, the reaction liquid of the acidic solution and the wax liquid is layered, and the lower layer liquid is pipetted;

[0031] Add vanillin to the lower layer liquid, stir evenly to form a mixed solution, check whether the mixed solution turns red;

[0032] If the mixture turns red, the candle contains iron.

Embodiment 2

[0034] An embodiment of the present invention provides a method for detecting the quality of a candle, which uses vanillin to detect iron in the candle. Specifically, the method includes:

[0035] Heat and melt the candle that may contain iron or the candle to be tested into wax liquid;

[0036] Slowly add hydrochloric acid solution with a concentration of 0.5mol / l into the wax liquid, stir evenly, and react;

[0037] After the reaction finishes, the reaction liquid of the acidic solution and the wax liquid is layered, and the lower layer liquid is pipetted;

[0038] Add vanillin to the lower layer liquid, stir evenly to form a mixed solution, check whether the mixed solution turns red;

[0039] If the mixture turns red, the candle contains iron.

Embodiment 3

[0041] An embodiment of the present invention provides a method for detecting the quality of a candle, which uses vanillin to detect iron in the candle. Specifically, the method includes:

[0042] Heat and melt 100g of candles that may contain iron or candles to be tested into wax liquid;

[0043] Slowly add nitric acid solution with a concentration of 0.5mol / l and a volume of 30ml into the wax liquid, stir evenly, and react;

[0044] After the reaction finishes, the reaction liquid of the acidic solution and the wax liquid is layered, and the lower layer liquid is pipetted;

[0045] Add vanillin to the lower layer liquid, stir evenly to form a mixed solution, check whether the mixed solution turns red;

[0046] If the mixture turns red, the candle contains iron.

Abstract

The invention provides a candle quality detection method and an application thereof. According to the invention, vanillin and iron ions in candle are subjected to a reaction to generate a blood red complexation iron product, whether the candle contains an iron element or not can be determined through color of a reaction object, and detection of the iron element in the candle can be realized by vanillin. The detection precision of the method can reach 0.001 g / ml, and therefore, the method can realize detection on the iron element for the low-iron content candle.

Description

technical field [0001] The invention relates to the technical field of daily chemical industry, in particular to a candle quality detection method and its application. Background technique [0002] Candle is a kind of common commodity in daily life. Candles are divided into two categories: daily lighting candles and handicraft candles according to different purposes. Daily lighting candles are relatively simple, generally white rod-shaped candles. Handicraft candles are divided into two categories: jelly craft candles and incense craft candles. Handicraft candles usually add ingredients showing different colors, and at the same time, they can be made into various shapes according to needs, which can integrate novelty, decoration, ornamental and functionality. Because candles can be prepared in different shapes and colors, etc., they are widely used in birthday parties, religious festivals, weddings and funerals, and activities to adjust the atmosphere. [0003] The main ...
