Abstract
The invention provides a method for rapidly detecting the quality of n-butyl acetate, which belongs to the technical field of raw material detection and comprises the following steps: weighing 0.2 +/-0.02 g of calcium isooctanoate liquid by using a triangular flask in a balance; transferring n-butyl acetate to be detected by using a pipette, slowly dripping the n-butyl acetate into a triangular flask, slowly shaking the triangular flask to dissolve calcium iso-octoate in the n-butyl acetate to be detected, observing appearance change of the mixed liquid, stopping adding the n-butyl acetate to be detected when the mixed liquid is white and turbid, and weighing and recording the adding amount of the n-butyl acetate to be detected; if the addition amount of the n-butyl acetate to be detected is less than 20g, the grade is determined to be unqualified, if the addition amount of the n-butyl acetate to be detected is 20-100g, the grade is determined to be qualified, and if the addition amount of the n-butyl acetate to be detected is more than 100g, the grade is determined to be superior. The invention has simple operation, low cost and high detection speed.
Description
Technical field
The invention belongs to raw material detection technique fields, and in particular to a kind of quick detection side of n-butyl acetate quality
Method.
Background technique
N-butyl acetate, abbreviation butyl acetate.The colorless and transparent liquid for having happy fruity smell.Lower level homologue indissoluble
Yu Shui；With the immiscible organic solvents such as alcohol, ether, ketone, it is a kind of excellent organic solvent, uses paint, curing agent, polyester resin extensively
Etc. industries.Calcium iso-octoate is light yellow clear liquid, is dissolved in ether, is slightly soluble in ethyl alcohol, and there is acid value to stablize, molecular weight stabilizers,
Lighter color, the advantage for urging dry effect good are mainly used as the drier of paint and the promotor of unsaturated polyester resin.Work as raw material
When n-butyl acetate poor quality, later period addition calcium iso-octoate is used as the promotion of the drier and unsaturated polyester resin of paint
When agent, it may occur that product whitens the quality problems of jaundice.And product is caused to whiten there are many reason of turning to be yellow, such as n-butyl acetate
Acid value is undesirable, the factors such as certain ions are reacted with calcium iso-octoate generation, and can not be to these in actual production
Project is detected one by one, is otherwise taken time and effort.
Summary of the invention
It is at low cost in view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of easy to operate, it detects fireballing
The rapid detection method of n-butyl acetate quality.
The present invention provides the following technical solutions:
A kind of rapid detection method of n-butyl acetate quality, comprising the following steps:
S1, in balance, with triangular flask weigh 0.2 ± 0.02g calcium iso-octoate liquid, balance zero；
S2, n-butyl acetate to be detected is pipetted with pipette and is slowly added drop-wise in triangular flask, while slowly rocking three
Angle bottle is dissolved in calcium iso-octoate in n-butyl acetate to be detected, observes the cosmetic variation of mixing liquid, when mixing liquid occurs
Stop adding n-butyl acetate to be detected when white opacity, and weighs the additive amount for recording n-butyl acetate to be detected；
S3, Quality estimation, if the additive amount of n-butyl acetate to be detected is less than 20g, n-butyl acetate quality test is sentenced
Be set to it is unqualified, if the additive amount of n-butyl acetate to be detected, in 20-100g, n-butyl acetate quality test is judged to closing
Lattice, if the additive amount of n-butyl acetate to be detected is greater than 100g, n-butyl acetate quality test is determined as top grade.
Preferably, the balance accuracy in the S1 is 0.01g.
Preferably, the volume of the S1 intermediate cam bottle is 250mL.
Preferably, the calcium iso-octoate liquid is that analysis is pure.
The beneficial effects of the present invention are: passing through Xiang Yixin using the simple laboratory apparatus such as balance, triangular flask, pipette
N-butyl acetate to be detected is added dropwise in sour calcium and weighs n-butyl acetate to be detected when white opacity occurs in observation mixed liquor
Content, then judge that the quality of n-butyl acetate, quality herein refer to whether acid value conforms to according to the weighing value
It asks, with the presence or absence of the certain ions to react with calcium iso-octoate, the detection method is easy to operate, and at low cost, detection speed is fast,
Routine Test Lab or factory condition are able to satisfy the test request, and applicability is wide.
Specific embodiment
Embodiment 1
A kind of rapid detection method of n-butyl acetate quality, comprising the following steps:
S1, in the balance that accuracy is 0.01g, weigh 0.2 ± 0.02g calcium iso-octoate liquid with the triangular flask of 250mL
(analysis is pure), balance zero；
S2, n-butyl acetate to be detected is pipetted with pipette and is slowly added drop-wise in triangular flask, while slowly rocking three
Angle bottle is dissolved in calcium iso-octoate in n-butyl acetate to be detected, observes the cosmetic variation of mixing liquid, when mixing liquid occurs
Stop adding n-butyl acetate to be detected when white opacity, and weighs the additive amount for recording n-butyl acetate to be detected；
S3, Quality estimation, if the additive amount of n-butyl acetate to be detected is less than 20g, n-butyl acetate quality test is sentenced
Be set to it is unqualified, if the additive amount of n-butyl acetate to be detected, in 20-100g, n-butyl acetate quality test is judged to closing
Lattice, if the additive amount of n-butyl acetate to be detected is greater than 100g, n-butyl acetate quality test is determined as top grade.
Embodiment 2
