Abstract
The invention discloses a rose-variety flower extract-containing formaldehyde color-change indicator. The rose-variety flower extract-containing formaldehyde color-change indicator comprises 0.01-3% by mass of rose-variety flower extract, 0.01-6% by mass of a hydroxylamine salt and 91-99.98% by mass of a carrier. After the hydroxylamine salt in the rose-variety flower extract-containing formaldehyde color-change indicator contacts with formaldehyde, the hydroxylamine salt and formaldehyde undergo a reaction so that an acid proton is released. The rose-variety flower extract has the characteristic of color change after contact with an acid and thus the rose-variety flower extract-containing formaldehyde color-change indicator has the characteristic of color change after contact with formaldehyde. The rose-variety flower extract-containing formaldehyde color-change indicator has the simple preparation method and good effects and is conducive to large-scale preparation and application of this type of formaldehyde detection products.
Description
Technical field
The invention belongs to plant extracts and Field of Fine Chemicals, be specifically related to a kind of formaldehyde color indicator that contains rose class floral extract.
Background technology
Formaldehyde has strong impulse smell.Volatile, be the carcinogen that a kind of toxicity is very strong.Be defined as carcinogen by the World Health Organization (WHO) at present.In China, formaldehyde has been listed in the chemical article of high poison, high pollution.Formaldehyde can produce intense stimulus to skin, eyes, mucous membrane, can cause that function of immune system is not normal, also can cause the damage of hepatic injury and nerve center system, can cause the diseases such as fetal anomaly, leukaemia, chronic respiratory disease, women's paramenia, acute depression, nasopharyngeal carcinoma.The mechanism of carcinogenesis of formaldehyde is mainly the reparation that causes commissure and DNA and protein commissure in DNA single chain and suppress DNA damage, or causes gene mutation, and then generation tumour cell and carcinogenic.
At present the formaldehyde pollution of indoor environment mainly stems from lower building materials, finishing material and furniture material, and free shape formaldehyde and urea-formaldehyde resin adhesive decompose the formaldehyde producing completely wherein to relate in resin raw material unreacted.In the time of wood-based plate release formaldehyde, release rate reduces over time, and temperature is higher, and formaldehyde discharges faster.
The main methods of indoor formaldehyde has at present: spectrophotometric colourimetry (AHMT, phenol reagent, diacetone, phloroglucin etc.), chromatography, adsorptive voltammetry, electrochemical sensor method, biology sensor method etc.These methods all need to use more complicated and professional instrument, and the data that obtain after measurement are too accurate, are obviously not suitable for the simple detection of family.
Summary of the invention
The object of the invention is the easy detection formaldehyde demand for family, adopt the raw material that is conveniently easy to get, make one and can have reasonable degree of accuracy, operation is convenient again, and effective time short test paper for formaldehyde detection/test solution again, detection that like this can the indoor easy concentration of formaldehyde of more convenient average family.
Object of the present invention can reach by following measures:
An indicator that contains rose class floral extract, is characterized in that: this indicator is made up of the component of following mass content:
Rose class floral extract 0.01～3%,
Hydroxylamine salt 0.01～6%,
Carrier 91～99.98%.
Described rose class flowers can be one or more in rose, Chinese rose or rose; Described hydroxylamine salt can be one or more in hydroxylamine sulfate, hydroxylamine hydrochloride, azanol phosphate, azanol chlorate, azanol formates, azanol acetate or azanol oxalates; Described carrier (solid) can be one or more in paper, silica gel, porcelain earth, aluminium oxide, aluminium hydroxide, silicon dioxide, zeolite, molecular sieve, attapulgite, clay, carclazyte, silico-aluminate or pottery; Described carrier (liquid) can be one or more in water, ethanol, methyl alcohol, n-propanol, isopropyl alcohol, normal butyl alcohol, isobutyl alcohol, acetone, MEK, butanone, ether, propyl ether or tetrahydrofuran.
Hydroxylamine salt ([NH in this indicator
3oH]
+) run into after formaldehyde, there is following reaction:
HCHO+[NH
3OH]
+→CH
2NOH+H
++H
2O
Discharge sour proton, and rose class floral extract has the advantages that to meet sour variable color, therefore this indicator has just had the feature that runs into formaldehyde variable color.
The present invention is based on the analytic thinking of natural goods chemistry and scientific formulation, one matter effect means in traditional detection method are abandoned, the convenience requirement using for family, utilize rose class floral extract to meet the feature of sour variable color, ingeniously introduce sour proton donor-hydroxylamine salt, be combined into a kind of novel formaldehyde examination indicator.This indicator both can load on solid carrier, made test paper for formaldehyde detection, particle or film, can load on liquid-carrier again, made formaldehyde examination test solution, reagent, detection box etc.Method is simple, respond well, is conducive to the extensive preparation and application of such formaldehyde examination product.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.

Embodiment 3:
0.05 gram of Fols Rosae extract and 0.05 gram of Hydroxylamine sulfate are dissolved in to formation indicator in 99.9 grams of ethanol/waters (1/1, w/w).This indicator runs into 20ppm formaldehyde gas, and indicator becomes light red.
Embodiment 4:
0.1 gram of Flos Rosae Rugosae extract and 0.1 gram of oxammonium hydrochloride are carried on 99.8 grams of silica gel particles and form indicator.This indicator runs into 100ppm formaldehyde gas, and indicator becomes redness.
Embodiment 5:
3 grams of rose extracts and 6 grams of oxammonium hydrochlorides are carried on 91 grams of silica gel particles and form indicator.This indicator runs into 1ppm formaldehyde gas, and indicator becomes redness.
Comparative example 1:
0.1 gram of Hydroxylamine sulfate is dissolved in 99.9 grams of ethanol and forms solution.This solution runs into 100ppm formaldehyde gas, fails to observe variable color.
Due to only of the present invention compared with representative instance in order to explain described in embodiment; not the present invention is done to any pro forma restriction; all work under identical invention spirit about any modification of the present invention or change; within all should being included in the category that the invention is intended to protection; with the person that is familiar with technique; can not depart under ultimate principle of the present invention its parameter is done to variation in various degree; be equal to or similar effect to scheme to reach, so it all should be regarded as not departing from during above-described the scope of the claims defines.
