Stage 1: “Sulfanil”
Condensation product of aminodiphenylamine sulphonic acid (I) and
chloranil (II).
Plant: (1) 2 cbm. Enamel kettle with fast stirrer. (2)
Filter press, 800 x 800.
Process: 100 kg. of (I) and 47
kg. of (II) are condensed in 475 l. water, with 17.5 kg. MgO as acid binding
agent, for 5-6 hours at 60℃. Test shows no unchanged chloranil. After cooling to 200, the batch
is filtered and the kettle rinsed out with the mother liquor. The product is
dried in vacuo at 70-800 to 85% total solids content.
The product is a dark blue powder, soluble in water to a dirty violet
colour.
Amounts used per ton of product:-
0.7 ton of (I) 0.35 ton of (II).
Stage 2: Sirius Light Blue FF2GL Powder.
Dioxazine from chloranil and 4-aminodiphenylamine-2-sulphonic acid.
Plant: (1) 3 cbm. C.I. vessel; C.I. cover; steam jacket;
enamel stirrer.
(2) Hydrolysis vessel; 6 cbm.; rubber and tile lined; cover is rubber lined; stirrer and lead coil.
(3) 2 x “Monster” presses, 1,200 x 1,200, dressed with nitrated cloth.
Process:
Into the 3 cbm. Reaction pan are charged 760 kg. H2SO4 (95%) and 820
kg. oleum (20%) to give approx. monohydrate (100%) strength. Then 1,120 kg.
oleum (20%) is added so that the final strength is 8.3% oleum. After cooling to
O℃., 135 kg. “Sulfanil” is added during 1/2
hour, whereby the temperature rises to 35℃. The batch is then heated to 50-55℃. and stirred at this temperature until Test
1 is satisfied. (Samples are taken 10 minutes after charging and thereafter at half-hour
intervals.). This takes 3-6 hours. If the reaction is slow the temperature is
maintained at 55℃.
The hydrolysis vessel is charged with 1,800 kg. ice and 300 l. water.
At 0℃., the
sulphonation mixture is blown over during 2 hours, with stirring. The temperature rises to 70-75℃. The
drowned out mass is heated during 3/4 hour to 100℃. and held for 16 hours at 95-100℃. (Test 2).
After cooling to 20℃. and diluted with 900 l. water, the dyestuff is filtered in the press
(Test 3) and washed with 20% brine (Test 4).
The press cake is slurried in the same vessel with 600 kg. brine 20% and
then neutralized with Na2CO3 solution (Test 5).
The dyestuff is filtered in the presses and dried in vacuo at 70-80℃.
Yield: 150 kg. Dry = 540 kg. Standard (17% colour content) = 95 kg.
Pure dyestuff.
Tests: 反应过程中控制分析点分析方法。
(1)A drop of the sulphonation mixture in 40 cc.
water and 15 cc. soda solution (30%) is reddish in the first hour and bluish
afterwards. The reaction is finished
when the yellow glass filter shows no colour difference in 3 consecutive tests. (2) 0.5 cc. Mixture with 5 cc. NaOH solution
(16%) and 20 cc. NaCl (25%) shaken and twice filtered. 1st test after 5 hours – faint blue; 1st test
after 10 hours – weaker blue; 1st test
after 16 hours – nearly colourless. (3)
Filtrate should be colourless. (4) H2SO4
in filtrate must be under 2%. (5) pH
7.3; colourless.

Light Blue FF2GL. 美国人的简单说明。
This dye was made from chloranil and 4-amino-diphenylamine-2-sulfonic
acid. Although the color was stated to
be quite deficient in washing fastness, it was believed to be of interest
because of its greener and somewhat brighter shade as compared with the F3GL
type.
