Abstract
A color stabilizer for preventing the color of phenol and alkylphenol from changing is composed of component A (hydrazine compound and/or hindered amine type photostabilizer) and component B hydroxyamine compound and/or 9,10-dihydro-9-oxa- 10-phospha phenanthrine-10-oxide (DPPO).
Description
Technical field
The present invention relates to a kind of phenols colour(ing)stabiliser, more specifically relate to a kind of inhibition phenol and alkylphenol discoloration, improve the composition of its appearance color stability.The invention still further relates to the application of this colour(ing)stabiliser.
Background technology
Phenol and alkylphenol are a kind of important organic synthesis raw materials, are widely used in the production of pharmacy, fuel, synthetic resins, insullac etc.The phenol and the variable color of alkylphenol product appearance of domestic production at present are very fast, and the situation of appearance color change often occurs, cause phenol and alkylphenol product memory cycle very short, are unfavorable for product application.
Prior art is studied utilizing stable reagent inhibition phenol and the variable color of alkylphenol product, it is reported that Japan adopts antioxidant that adds the 0.001-2.0% that accounts for phenol and alkylphenol product weight or the storage period that azanol class compositions and methods prolongs phenol products.For example add 9 in phenol, cresols and xylenol, the 10-dihydro-9-oxy is mixed-10-phospho hetero phenanthrene-10-oxide compound (DPPO), can store nondiscoloration in 60 days; The salt reagent that in phenol and alkylphenol product, adds diethyl hydroxylamine (DEHA), diethyl hydroxylamine also can reach identical effect (fuel and chemical industry, 1986,2:36).Chinese invention patent application 02132533.2 discloses a kind of compound colour(ing)stabiliser that suppresses phenol and alkylphenol discoloration, this stablizer is made up of P contained compound and sequestrant, in phenol and alkylphenol, add this compound colour(ing)stabiliser and can suppress variable color, improve the color stability of phenol and alkylphenol, and the inhibition color changeable effect of this compound colour(ing)stabiliser is not subjected to product purity, moisture, the influence of factors such as metallic impurity kind, but this compound colour(ing)stabiliser contains P contained compound, and more inapplicable required phenol and the alkylphenol product of technology that P contained compound is had the side effect reaction.
The existing colour(ing)stabiliser that is used for phenol and alkylphenol product exists and keeps the product appearance colour stable time shorter, and certain defectives such as side effect are arranged.
Summary of the invention
The purpose of this invention is to provide a kind of phenol and alkylphenol colour(ing)stabiliser, use preservation that this stablizer can make phenol and alkylphenol product effectively more than 90 days and nondiscoloration, thereby overcome the deficiencies in the prior art.Another object of the present invention provides the purposes of this stablizer.
Colour(ing)stabiliser of the present invention is made up of the A reagent of 1-1000 weight part and the B reagent of 0-500 weight parts, wherein said A reagent refers to carbohydrazide or hindered amine light stabilizer or their mixture, wherein the preferred Tinuvin-622 reagent of hindered amine light stabilizer, Tinuvin-770 reagent, Tinuvin-5178 reagent or their mixture; Said B reagent refers to hydroxylamine compound, 9, and the 10-dihydro-9-oxy is mixed-10-phospho hetero phenanthrene-10-oxide compound (DPPO) or their mixture, the wherein preferred diethyl hydroxylamine of hydroxylamine compound.A reagent and B reagent are promptly got colour(ing)stabiliser of the present invention by above-mentioned formula rate mixing.
According to the present invention, this colour(ing)stabiliser is used for suppressing by resulting phenol of industrial production and alkylphenol product, and its consumption is every processing 1000 gram phenol or alkylphenols, and the colour(ing)stabiliser that is consumed is made up of 0.01-10 gram A reagent and 0-5 gram B reagent.The usage of colour(ing)stabiliser of the present invention is: make phenol and alkylphenol product keep liquid state by the heat tracing mode, add colour(ing)stabiliser of the present invention after, mix.
Beneficial effect
1, colour(ing)stabiliser of the present invention can suppress phenol and the variable color of alkylphenol product effectively, improves the stability of its appearance color, uses behind the colour(ing)stabiliser of the present invention to keep appearance white storing more than 90 days.
2, colour(ing)stabiliser of the present invention does not contain P contained compound substantially, uses simply, and side effect is low.
