43830)资料抄录如下 (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°C and 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°C by 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°C add 50kg sodium nitrite. Agitate 1 hour at 15-20°C Then heat to 60°C as 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!
