(其中CAS号为本人所加):
To a 1500L enameled kettle add 1300kg 100% sulfuric acid and
660kg 60°Be’ sulfuric acid. Cool to 20-25°C
and add 200kg 2,6-dichloro benzaldehyde [83-38-5] as moist
paste(84-90%). Heat to 50°C to dissolve.
Cool to 30°Cand skim off any tar which
separates. Cool to 20°C and transfer to
7000L lead-lined kettle. During 6 hours at
15-20°C add 376kg o-cresotinic acid
[83-40-9]. Agitate 12 hours at 20-25°C
and test. Drown 200mL mess in 600g ice and water. Filter and
wash acid-free. Dissolve the ckae at
5-10°Cby making just alkaline with sodium
hydroxide and dilute to 600mL Filter off any unreacted aldehyde.
Heat filtrate to 80-90°C and add
hydrochloric acid in 300mL water equivalent to sodium hydroxide
used to dissolve the color. Filter off leuco, wash, dry and weigh.
Yield should be 95-97% of theoretical. Cool filtrate and salt to
precipitate any excess o-cresotic acid. There should be no
unreacted aldehyde or cresotinic acid. If there is, add aldehyde or
cresotinic acid and condense further.
When correct adjust to 94-95% acid by analysis, by adding
about 535kg 100% sulfuric acid. Then during 6 hours at
15-20°Cadd 50kg sodium nitrite. Agitate 1
hour at 15-20°C Then heat to
60°Cas quickly as possible but watch for
severe frothing. Hold 1 hour and then test. Drown sample equivalent
to 10g aldehyde in ice and water. Filter off color, wash acid-free,
dissolve with aqueous sodium hydroxide, and dilute to 1 liter.
Dilute 14.2mL of theis solution and 5mL concentrated sodium
hydroxide. Compare in colorimiter with standard similarly prepared.
Hold charge at 60°C and test every hour
until yield no longer increases. When finished drown in 7000L ice
and water. Filter. Agitate cake with 7000L water. Filter and wash
essentially acid-free.
Add cake to 1000L water containing 300kg 48% sodium
hydroxide. Heat to 85°C to dissolve. Salt
out with 500kg salt. Filter on nutsch. Dry in vacuo at
95°C The yield was 615kg dry weight
equivalent to 1500kg Chromoxane Pure Blue B.
From the filtrate a dukk product, Chromoxane Blue BX for
mixing or shading may be recovered by acidification.

上网资料小结
【关于新技术,新应用】因为在以前上网的资料中,未提及到它,今天补充一下。如《发光色素-Luminescent
CoLorant》。发光色素是指在适当(可见光,红外光或紫外光)激励下,一种可发出光的色素,BASF产品以Lumogen命名。
【已上网的有】Lumogen LT Bright
Yellow,其CAS号[2387-03-3];Lumogen
Yellow
Orange,其CAS号[959-36-4],两者分别在2016年4月18日和2017年6月20日上网。在这里再次谢谢公司给本人提供上网的条件!当然也要谢谢读者的点读!
