Abstract
The present invention relates to a kind of method of lignin phenolate, step is as follows：(1) by lignin solid, NaOH solids and water, heating condition carries out reaction certain hour；(2) a certain amount of phenol solid and NaOH solids are added, continues to react can obtain the modified lignin of phenolate.The present invention uses lignin portion fortified phenol; wide material sources, and it is cheap, so greatly reducing production cost; the present situation that lignin in nature is largely wasted is also solved, is that the protection of ecological environment and the recycling of discarded object also provide a paths.
Description
Technical field
The present invention relates to material and chemical technology field, more particularly to a kind of method of lignin phenolate.
Background technology
There is substantial amounts of aldehyde radical and hydroxyl in its structure as a kind of natural polyphenol family macromolecule polymer in lignin, therefore
This can with phenol and formaldehyde novolak resin when reduce the consumption of phenol and formaldehyde.Meanwhile, pass through light on the earth every year
About 150,000,000,000 tons of the lignin of cooperation synthesis；Only in paper-making pulping production process, isolated by raw material of string
Xylogen by-product also have about 50,000,000 tons/year, also the form of " black liquor " is directly discharged into natural water mostly, portion of product
Burned after being concentrated, the lignin being utilized effectively is less than 20%.
There is substantial amounts of aldehyde radical and hydroxyl in its structure as a kind of natural polyphenol family macromolecule polymer in lignin, therefore
This can with phenol and formaldehyde novolak resin when reduce the consumption of phenol and formaldehyde.But current natural lignin's activity
It is relatively low, influence the popularization in synthetic resin material of lignin.
The content of the invention
The present invention is a kind of method provided by the present invention to provide method of lignin phenolate, reaches what is extracted
Lignin good dispersion, activity purpose higher.
Technical scheme is as follows：
(1) lignin solid, NaOH solids and deionized water are mixed, agitating heating is for a period of time；
(2) to a certain amount of phenol solid and NaOH solids is added in reaction solution in step (1), one section of agitating heating is continued
Time is that can obtain phenolate lignin liquor.
Further, NaOH solids and the mass ratio of lignin solid are 0.5 in step (1):100~100:100, go from
Sub- water quality is 10~50 times of lignin solid masses.
Further, the quality of phenol and the mass ratio of lignin solid are 1 in step (2):100~90:100, NaOH
Solid is 0.1 with the mass ratio of lignin solid:100~50:100.
The present invention has following superiority：
(1) it is of the invention due to using phenol activation lignin, and by adding NaOH solids twice so that log quality
Activated with the great amount of hydroxy group in phenol, increased the activation grade of lignin function group；
(2) the activation lignin that the present invention is obtained can be used to replace the phenol in various resins synthesis so that phenol
Consumption is minimized, and reduces production cost, and environment is also protected to a certain extent, embodies the theory of Green Chemistry.

The lignin of activation modification can be obtained.
Embodiment two
(1) lignin 4g, NaOH solid 2g, deionized water 100g are added in 250mL there-necked flasks, 90 DEG C are warming up to,
Heating stirring 24h；
(2) to phenol 1g, NaOH solid 0.4g is added in above-mentioned reaction solution, 70 DEG C are incubated, continue heating stirring 1h.
Obtain the lignin of activation modification.
Embodiment three
(1) lignin 2g, NaOH solid 2g, deionized water 100g are added in 250mL there-necked flasks, 80 DEG C are warming up to,
Heating stirring 20h；
(2) to phenol 1g, NaOH solid 0.5g is added in above-mentioned reaction solution, 90 DEG C are incubated, continue heating stirring 12h.I.e.
The lignin of activation modification can be obtained.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
Specific implementation of the invention is confined to these explanations.For the personnel of the technical field of the invention, this is not being departed from
On the premise of inventive concept, many simple deduction or replace can be also made, should all be considered as belonging to protection scope of the present invention.
