Abstract
The invention provides refraction liquid, which can be matched with the refractive rate of fused quartz glass, is stable and actually non-toxic and has small smell. The refraction liquid is prepared by completely exposing raw materials, namely isopropyl myristate which is non-toxic and tasteless and ethyl cinnamate with light enduring cinnamon and strawberry aroma and sweet honey aroma at normal temperature and under normal pressure for 24 hours, and has the refractive rate of less than 5*10<-5> and higher stability. Therefore, high accuracy of the refraction liquid can be kept in the testing process for a relatively long time; in addition, the refraction liquid is actually non-toxic and has small smell, so that influences of stronger smell of the refraction liquid in an airtight space on testing personnel are eliminated.
Description
Technical field
The present invention relates to a kind of REFRACTIVE LIQUID that is used for common optical glass test usefulness, be specially adapted to the fused quartz glass test and use REFRACTIVE LIQUID, and stablize harmless.
Background technology
When character such as the homogeneity of measuring optical glass, stress birefrin, need smear the REFRACTIVE LIQUID that is complementary with it according to the refractive index value of glass.Common REFRACTIVE LIQUID is by kerosene, alpha-bromonaphthalene at present, and the sulphur saturated solution of diiodomethane, diiodomethane etc. are formulated.These solution great majority all have the toxicity of medium tenacity, are 810mg/kg (rat are through abdomen) like the LD50 of alpha-bromonaphthalene, and diiodomethane LD50 is 403mg/kg (rat is through abdomen), belongs to the moderate toxicity material basically.Kerosene has bigger smell, and volatility is stronger.
One Chinese patent application number is 201010293378.7 to disclose " environmental protection REFRACTIVE LIQUID ", is used for the homogeneity of optical glass, the test of stress birefrin.It is characterized in that: the REFRACTIVE LIQUID of the potpourri preparation different refractivity of one or both in employing caryophyllus oil and the soybean oil, its ranges of indices of refraction is 1.471～1.5410, can not be as the matching fluid of high precision measurement fused quartz glass.
Periodical " the geology opinion is commented " the 22nd volume the 4th periodical has been stepped on article " index of refraction (n
22 ℃=1.402～2.004) immersion oil compound method ".It is 1.402～1.450,1.450～1.630 and 1.630～2.004 REFRACTIVE LIQUID that this article divides three series to prepare refractive index respectively, formulated by in the distillation of kerosene (or gasoline), α-Lv Dainai, diiodomethane, the arsenic tribromide one or both.
More than in the REFRACTIVE LIQUID preparation program of report, high volatility, caryophyllus oil or kerosene that smell is heavier are arranged all, stability is not good enough.In addition, the ranges of indices of refraction of environmental protection REFRACTIVE LIQUID is narrower, the matching fluid in the time of can not be as high-precision measuring fused quartz (Nd=1.4584～1.4587).
In sum, do not see and stablize nontoxic and can be used for the report of the REFRACTIVE LIQUID of high-acruracy survey fused quartz glass.
Summary of the invention
Deficiency to above-mentioned prior art existence; The present invention proposes a kind of glass test and use REFRACTIVE LIQUID; The REFRACTIVE LIQUID that can be complementary with the fused quartz glass refractive index; Adopt isopropyl myristate or ethyl cinnamate as REFRACTIVE LIQUID, or two kinds of mixed preparing are formed, the refractive index of said REFRACTIVE LIQUID is 1.4346～1.5588.
REFRACTIVE LIQUID use in glass of the present invention test, and under normal pressure, 20 ℃ of conditions, the employing isopropyl myristate obtains refractive index and be 1.4346 REFRACTIVE LIQUID.
REFRACTIVE LIQUID use in glass of the present invention test, under normal pressure, 20 ℃ of conditions, isopropyl myristate and ethyl cinnamate be by volume 100: 23.69 mixed must, refractive index is 1.4587.
REFRACTIVE LIQUID use in glass of the present invention test, under normal pressure, 20 ℃ of conditions, isopropyl myristate and ethyl cinnamate be by volume 100: 39.05 mixed must, refractive index is 1.4700.
REFRACTIVE LIQUID use in glass of the present invention test, under normal pressure, 20 ℃ of conditions, isopropyl myristate and ethyl cinnamate be by volume 100: 140.06 mixed must, refractive index is 1.5080.
REFRACTIVE LIQUID use in glass of the present invention test, at normal pressure, 20 ℃ the time under the condition, isopropyl myristate and ethyl cinnamate be by volume 100: 185.87 mixed must, refractive index is 1.5164.
REFRACTIVE LIQUID use in glass of the present invention test, under normal pressure, 20 ℃ of conditions, isopropyl myristate and ethyl cinnamate be by volume 100: 723.59 mixed must, refractive index is 1.5430.
REFRACTIVE LIQUID use in glass of the present invention test, and under normal pressure, 20 ℃ of conditions, the employing ethyl cinnamate obtains refractive index and be 1.5588 REFRACTIVE LIQUID.
REFRACTIVE LIQUID is used in glass test provided by the invention, exposes 24 hours at normal temperatures and pressures fully, and its variations in refractive index is less than 5*10
-5, reality is nontoxic and smell is little.Its ranges of indices of refraction is 1.4346～1.5588, has contained the ranges of indices of refraction of optical glass commonly used basically.
