Embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to described reality
Apply among a scope.The experimental method of unreceipted actual conditions in the following example, conventionally and condition, or according to business
Product specification is selected.
The compound I-1 of embodiment 1 preparation
Step a):Prepare compound III
8mL sodium hydroxide solutions (100g/L) are added into 0.01mol 4,4- -2,2 '-disulfonic acid of diaminobenzil
In the 30mL aqueous solution, the pH value for making solution is 7, stand-by.Separately 0.02mol Cyanuric Chlorides (compound V) are beaten in 30mL water,
After after mashing fully, above-mentioned 4,4- diaminobenzil -2 are added thereto, 2 '-sodium disulfonate solution is added for about 1 hour,
Reacted 2~4 hours between pH value 1~7 after adding, obtain compound III crude product.
Step b):Compound II-1 preparation
By 0.02molR2H-1 10.6mL sodium carbonate liquors (100g/L) dissolve, and the pH value for making solution is 6~7, then,
In the crude product that this solution is added to the compound III-1 obtained by step a), 30~40 DEG C are warming up to, 5~7 hours are incubated, protected
PH value 4~7 is held, compound II-1 crude product is made.
Step c):Compound I-1 preparation
In the crude product that 0.03mol diethanol amine is added to the compound II-1 obtained by step b), 80~100 are warming up to
DEG C, back flow reaction 4~8 hours in the temperature range, reaction terminates, and in 130~135 DEG C of spray drying, obtains compound I-
1, yield 85%, HPLC purity is about 95%.
It is 1733 to test its molecular weight by HPLC-MS, is consistent with its structure.
Embodiment 2-9
Operated according to the identical of embodiment 1, differ only in the R with corresponding construction2H and R1H, it is as a result as follows:
Effect example
The compound I of synthesis and convenience goods 4BK is subjected to cotton dyeing, and by GB/T 8424.2-2001 and GB/T
The whiteness value and washing fastness of 3921.3-1997 methods describeds test dyed fabric, are contrasted.After dyeing fastness grading according to
Standard GB/T/T 250-2008.
The consumption for synthesizing compound I is 0.3% (o.w.f), and sodium sulphate 20g/L is separately added into after weighing.Dissolving is added
After cotton immersion 5min, dye bath was warming up to 60 degree in 20 minutes, after maintaining 30 minutes, added sodium carbonate 5g/L.Continue to be incubated
30 minutes.Take out cold water wash.
Sell conventional cotton fluorescer 4BK (being purchased from Zhejiang Anoky Additives Co., Ltd.) dyeing consumption 0.3% in market
(o.w.f) sodium sulphate 10g/L, is added after weighing.Dissolving is added after cotton immersion 5min, and dye bath was warming up to 98 in 20 minutes
Degree, continues to be incubated 30 minutes.Take out cold water wash.
The lustful cloth specimen of above-mentioned dye is washed 15 minutes at 95 degree with soaping agent 2g/L.
As can be seen here:The present invention, which obtains a class, can improve the not enough fluorescent whitening agent of prior art, and its whiteness is higher than market
Product, washing is faded less, and washing fastness is outstanding.And due to being contaminated in middle temperature (60 degree), hence it is evident that than the 4BK of 98 degree of high-temperature dyeings
More to save the energy.
