Abstract
The invention belongs to chemicals technical field, it is related to a kind of low condensation point phosphoric acid, formula to include the deionized water of 75~80wt% phosphoric acid, 0.1~3wt% methyl alcohol, 0.1~3wt% ethylene glycol and surplus.This phosphoric acid makes the freezing point can be reduced to less than 0 DEG C on the premise of valid density is ensured, normal temperature state viscosity is less than the nearly half of 80% phosphoric acid, can keep more preferable mobility, the use demand in adaptation hi-tech industry.
Description
Technical field
It is more particularly to a kind of to use the more preferably low condensation point phosphoric acid of universality the present invention relates to chemicals technical field.
Background technology
Phosphoric acid (chemical formula:H3PO4) it is a kind of common inorganic middle strong acid, it is in TFT-LCD, TP, antirust agent, food additive
Plus agent, dentistry and orthopaedic srugery, EDIC corrosive agent, electrolyte, scaling powder, dispersant, industrial corrosion agent, the raw material of fertilizer and group
There is application on part household cleaning product.
The freezing point of common 80% concentration phosphoric acid is at 21 DEG C or so, that is to say, that less than this temperature, and phosphoric acid will start to coagulate
Consolidate and become sticky.But this freezing point is in the domain of walker of power house environment temperature, if used in the winter time, environment temperature
Degree is just likely to less than this freezing point, such phosphoric acid will retrogradation, mobility is deteriorated and leads to not use.Although phosphoric acid is dense
Degree reduction can cause the freezing point to reduce, but this can cause waste water to increase, and can not at will change in some hi-tech industries
Become the valid density of phosphoric acid.
Problem above is solved it is therefore desirable to develop a kind of phosphoric acid of low condensation point.
The content of the invention
It is a kind of using the more preferably low condensation point phosphoric acid of universality it is a primary object of the present invention to provide.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of low condensation point phosphoric acid, formula includes 75~80wt% phosphoric acid, 0.1~3wt% methyl alcohol, 0.1~3wt% ethylene glycol
With the deionized water of surplus
Specifically, formula includes the deionized water of 75wt% phosphoric acid, 0.1wt% methyl alcohol, 3wt% ethylene glycol and surplus.
Specifically, formula includes the deionized water of 80wt% phosphoric acid, 3wt% methyl alcohol, 0.1wt% ethylene glycol and surplus.
Specifically, formula includes the deionized water of 76.8wt% phosphoric acid, 2wt% methyl alcohol, 2wt% ethylene glycol and surplus.
Specifically, formula includes the deionized water of 77wt% phosphoric acid, 1wt% methyl alcohol, 1.5wt% ethylene glycol and surplus.
Specifically, formula includes the deionized water of 76wt% phosphoric acid, 2.5wt% methyl alcohol, 1wt% ethylene glycol and surplus.
Using above-mentioned technical proposal, the beneficial effect of technical solution of the present invention is：
This phosphoric acid makes the freezing point can be reduced to less than 0 DEG C on the premise of valid density is ensured, normal temperature state viscosity is low
In the nearly half of 80% phosphoric acid, more preferable mobility can be kept, adapt to the use demand in hi-tech industry.
Specific embodiment
The present invention is described in further detail with reference to specific embodiment.
Embodiment 1~5：
According to the deionized water of 75~80wt% phosphoric acid, 0.1~3wt% methyl alcohol, 0.1~3wt% ethylene glycol and surplus
Be well mixed for raw material by proportioning, obtains low condensation point phosphoric acid.
Detailed composition is as shown in table 1：
Table 1：
Explanation：The part of embodiment constituent mass percentage insufficient total amount is deionized water in table 1.
Using 80% phosphoric acid as reference examples, experiment is compared with the low condensation point phosphoric acid of gained of embodiment 1~5.
Test method：
1. reference examples and embodiment phosphoric acid are freezed, is then heated up naturally and temperature of the measurement, it is bent by drawing Temperature-time
Line finds the freezing point of this phosphoric acid.
2. at a temperature of 25 DEG C according to《GB/T 10247-2008 Viscosity Measurement Methods》Phosphoric acid viscosity is detected.
Contrast situation is shown in Table 2：
Table 2：
As shown in Table 2, this phosphoric acid makes the freezing point can be reduced to less than 0 DEG C on the premise of valid density is ensured, can be with
Substantially ensure at general temperature, this phosphoric acid will not occur to solidify and influence to use in advance；Compared to common 80% phosphoric acid, its
Normal temperature state viscosity is less than the nearly half of 80% phosphoric acid, therefore, it is possible to keep more preferable mobility, making in adaptation hi-tech industry
With demand, with the good market competitiveness, or even can be promoted the use of in some high-quality precision and sophisticated technology fields.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
Enclose.
