Lithol Fast Red Toner R    Jan. 21, 1942.  （注：译文按德文格式，我改动了。）

Trade Name:  Litholechtrot toner R (Hoe.) - 这是德文。

Composition: 我改成反应式：

2-氨基-4-苄基磺酰基苯甲醚 à à 3-羟基-2’,3’-二甲基-2-萘甲酰苯胺  à  C.I.颜料红163 (C.I. 12455)

Principal uses:  Printing ink.    Batch size:   0.3 mol   Process:   Diazo
  800 l. H₂O and 36.9 kg (译文，漏了) HCl (202 l. 5 N HCl) are run into diazo vat and heated to 25⁰C (文中是75⁰C，错了), then 83.1 kg (文中是83 kg) Orthosinsulfobenzyl (1-methoxy-3-aminophenyl-4-benzyl sulfone) are  Added. The base dissolves very quickly. 1300 kg ice are added and temperature adjusted to 0⁰C. To this is added immediately and rapidly under the suface 39.4 l. (文中是39.5 L) 40% NaNO₂ solution (20.7 kg NaNO₂ 100%) Stirring is continued for 1 ¹/₂ hrs (未译) and the temperature held at 0⁰C. Reaction should be weak on starch KI paper (未译). Volume diazo is made to 2400 l. and temperature to 0⁰C. 6 kg Carboraffin * is added and the diazo stirred for 1/4 hr. Agitation of the diazo is discontinued during coupling.
Coupling Component
  1000 l. H₂O and 105 l. 33% NaOH solution (47 kg NaOH) are heated to 85⁰C. To this is added 96 kg meta-xylidide of BON and the temperature held at 80-85⁰C for 10 minutes. 6 kg Kieselgur are added and the solution is clarified thru a press and filtrate run to the coupling vat. The solution vat is washed with 300 l. H₂O thru the press. Volume in coupling vat is made to 2000 l. and 18 kg Igepon T ** Dissolved in 200 l H₂O are added. (译文不清，不是膏状物). The solution is cooled with ±1600 kg ice to 2⁰C and precipitated with 250 l. HCl 5 N over 1/4 hr. under agitation. Reaction definite on Congo Red. 200 kg Sodium acetate crystals are then added.
Coupling
  The precipitate of the arylide is heated to 42⁰C and at this temperature  the diazo solution is run in under the surface, after first clarifying thru a filter press – over 2¹/2 hrs.(不是2-2.5 h). The temperature is held at 42⁰C. No excess diazo solution is permissible. The pigment is stirred for 15 minutes, filtered and washed 2 hrs.    * Carboraffin = clarifying carbon  ⁸⁸ Igepon T = CAS No.:[137-20-2]
