Abstract
The invention provides an environment-friendly refraction liquid, which adopts one or more than one of clove oil and soybean oil. Because adopting nontoxic and harmless clove oil and soybean oil, the refraction liquid is prevented from harms to bodies of testers, and the worries of the testers are eliminated, a solid foundation for the accurate test of data is laid. In addition, the environment-friendly refraction liquid has low cost compared with a traditional refraction liquid, and reduces the operation cost.
Description
Technical field
The present invention relates to a kind of environmental protection REFRACTIVE LIQUID that is used for the optical glass test.
Background technology
When the optical homogeneity of measuring optical glass, stress birefrin character, need use the REFRACTIVE LIQUID of different refractivity.At present used REFRACTIVE LIQUID has naphthalene bromide, diiodomethane, arsenones etc., but these organism all are noxious materials, and tester's respiratory tract, skin etc. are had bigger harm, has had a strong impact on the healthy of tester.
Summary of the invention
Technical matters to be solved by this invention provides a kind of REFRACTIVE LIQUID of environmental protectionization.
The technical scheme that technical solution problem of the present invention is adopted is: the environmental protection REFRACTIVE LIQUID is characterized in that: one or more in employing caryophyllus oil and the soybean oil are as REFRACTIVE LIQUID.
Further, adopt the caryophyllus oil and the soybean oil of arbitrary volume ratio, or wherein a kind of in caryophyllus oil and the soybean oil, obtain refractive index and be 1.471～1.5410 REFRACTIVE LIQUID.
The invention has the beneficial effects as follows: because REFRACTIVE LIQUID of the present invention adopts nontoxic caryophyllus oil and soybean oil, avoided the actual bodily harm of REFRACTIVE LIQUID to the tester, the tester does not worry when testing, and has established the basis that accurate test data is provided.In addition, the more traditional REFRACTIVE LIQUID cost of environmental protection REFRACTIVE LIQUID of the present invention is low, the operation cost that has reduced.
Embodiment
The present invention adopts caryophyllus oil and soybean oil as base oil by repetition test, by changing volume ratio between the two, or only adopts wherein a kind of in caryophyllus oil and the soybean oil, can obtain refractive index and be 1.471～1.5410 REFRACTIVE LIQUID.
Above-mentioned caryophyllus oil molecular formula: C
10H
12O
2, molecular weight: 164.20, colourless or weak yellow liquid.Fusing point-9.2～9.1 ℃, 253.2 ℃ of boiling points, relative density 1.038～1.060 (4～20 ℃ relative densities), refractive index 1.5410.Can be miscible with alcohol, ether, chloroform, volatile oil, be dissolved in glacial acetic acid and caustic solution, water insoluble.Color deepens retrogradation gradually in air.This material can become blue with red reindeer moss, is blue with the ethanolic solution effect of ferric trichloride.
Above-mentioned soybean oil is the semi-drying oil that is obtained by soybean (oil-containing about 15～26%).Relative density 0.9150～0.9375 (4～20 ℃ relative densities), refractive index 1.471-1.475, test by experiment, gourmet's luck soybean oil refractive index 1.4718, golden imperial fish soybean oil refractive index 1.4715, fragrant gardenful soybean oil refractive index 1.4712.Above-mentioned soybean oil iodine number 120～141, acid number≤3, saponification number 189～195.Principal ingredient is the glyceride of linoleic plus oleic acid.Rough soya-bean oil is yellowish-brown or rufous, because of containing a large amount of phosphide class (1～3%) impurity, need carry out refinement treatment before therefore using.Soybean oil is mainly edible, also is used to make fixed oil, soap, glycerine and paint etc.
The fatty acid constituent (%) of soybean oil is: palmitic acid 6～8%, oleic acid 25～36%, stearic acid 3～5%, linoleic acid 52～62%, leukotrienes 2～3%.Crude oil of soybean has fishy smell, can remove after the refining, but the aftertaste tendency is arranged in the storage.Beany flavor because contain leukotrienes, isoiinolic acid causes, with the selection hydrogenation method linolenic acid content is reduced to minimum, avoid the generation of isoiinolic acid simultaneously, then can eliminate " aftertaste " phenomenon of soybean oil substantially.Refined soybean oil is when long-term storage, and its color can be from light to dark, and this phenomenon is called " color recovery ".The color recovery phenomenon of soybean oil is all more remarkable than other grease, and the caused complicated variation of grease autoxidation may be its fundamental cause.The method of taking to reduce moisture content of raw material can prevent from the generation of this phenomenon to have solved the soybean oil color and luster basically.
Above-mentioned linoleic acid molecular formula: CH3 (CH2) 4CH=CHCH2CH=CH (CH2) 7COOH.[formal name used at school is suitable, and is suitable-9,12-18 (carbon) dienoic acid].Linoleic acid is with other fatty acid, is present in the animal and plant fat with the form of glyceride.Content in the animal tallow is generally lower, and for being 1.8%, lard is 6% as butter; Content is higher in some vegetable oil, is 26% as peanut oil, and soya-bean oil is 57.5%, and rape oil is 15.8%.Linoleic acid is a colourless oil liquid.Fusing point-5 ℃, 229～230 ℃ of boiling points (16 mm Hg), relative density 0.9022 (4～20 ℃ relative densities).Water insoluble, be dissolved in the organic solvents such as ether, chloroform.Autoxidation easily takes place in air.At 200 ℃ or when handling, change trans-linoleic acid with selenium into nitrogen oxides.Become 12-18 (carbon) olefin(e) acid and oleic acid during hydrogenation earlier, further hydrogenation becomes stearic acid.Linoleic acid is a fatty acid essential in the humans and animals nutrition.Linoleic sodium salt or sylvite are one of compositions of soap, and can be used as surfactants such as emulsifying agent.Pharmaceutically can be used for treating disease such as the too high and artery sclerosis of blood fat.Its aluminium salt can be used for making paint, coating etc.
The glyceride of above-mentioned oleic acid claims fatty glyceride again.Be often referred to by glycerine and fatty acid (saturated with undersaturated) through ester class that esterification generated.Can be divided into glycerine-(fat) acid esters C3H5 (OH) 2 (OCOR), glycerine two (fat) acid esters C3H5 (OH) (OCOR) 2 and glycerine three (fat) acid esters C3H5 (OCOR) 3 according to the number of used fatty acid molecule.The glyceride of high carbon number fatty acid (being commonly called as higher fatty acid) is the principal ingredient of natural oil.Wherein the most important thing is triglyceride, as olein (olein), palmitin (palmitin) and glycerol tristearate (stearin).Glyceride is neutral substance, and is water insoluble, is dissolved in organic solvent, and hydrolysis can take place.For example grease generates the sodium salt (hard soap, i.e. common soap) and the glycerine of high carbon number fatty acid with caustic soda hydrolysis (saponification) back.
Above-mentioned oleic acid is a kind of fatty acid, molecular formula C18H34O2, skeleton symbol CH3 (CH2) 7CH=CH (CH2) 7COOH, formal name used at school cis-9-+ eight (carbon) olefin(e) acid.Oleic acid is with other fatty acid, is present in all animal and plant fats with the form of glyceride.In animal tallow, oleic acid accounts for 40～50% in fatty acid.Variation in vegetable oil is bigger, can reach 54% in the peanut oil up to 83% in the tea oil, then has only 5～6% in the coconut oil.Pure oleic acid is colourless oil liquid.16.3 ℃ of fusing points, 286 ℃ of boiling points (100 mm Hg), relative density 0.8935 (4 ℃ relative densities).Be soluble in the organic solvents such as ethanol, ether, chloroform.Oleic acid and nitric acid effect, then isomery turns to trans-isomer, and the fusing point of elaidic acid is 44～45 ℃, and hydrogenation then gets stearic acid.Then get the potpourri of pelargonic acid and azelaic acid with potassium permanganate oxidation.Autooxidation can take place owing to contain two keys in oleic acid when the medium-term and long-term placement of air, the part is transformed into the material that contains carbonyl, and corrupt rancidity is arranged, and this is the reason of grease deterioration.In the commodity oleic acid, generally contain 7～12% saturated fatty acid, as palmitic acid and stearic acid etc.The sodium salt of oleic acid or sylvite are one of compositions of soap.Pure sodium oleate has good dirt-removing power, can be used as surfactants such as emulsifying agent, and can be used for treating cholelithiasis.Other slaines of oleic acid also can be used for aspects such as waterproof fabric, lubricant, brilliant polish, and its barium salt can be made rat poison.
