Application of Guaiazulene
Guaiazulene can be used as a starting product for the synthesis of:
- Azulene based dye molecules, such as 3- (7-isopropyl-1,4-dimethylazulen-3-yl) – 2-cyanoacrylic acid as well as 5- (7-isopropyl-1,4-dimethylazulen-3-yl) – 2-cyanopentadiene-2,4-dienoic acid.
- Stilbazulenyl nitrone, the 2nd generation azulene nitrone, can be utilized as a chain splitting antioxidant.
- Near infrared fluorescence quencher based upon BIS azulenyl.
Preparation of Guaiazulene
10 Kg of guacum officinale gum was heated to 130 ° C with 3-4 kg of sulfur. Slowly continue heating to 220 ° C under nitrogen. The water vapor formed is removed with a nitrogen gas stream. The temperature should be above 100 ° C so that water does not fall into the reaction mixture. H2S was obtained by dehydrogenation and removed with steam. Hydrogen sulfide is connected in the alkali trap.
When the H 2S discharge was stopped, the temperature was reduced to 120 ° C and the reaction mixture was distilled in vacuum for 1-20 mm. The distillate is dark blue and contains 6-7 kg of oil and 20% of 7-isopropyl-1,4-dimethyl azulene. It is dissolved in 5-10 volumes of light petroleum, shaken with sodium hydroxide to remove sulfur-containing substances, and washed to neutral. The oil layer is then mixed with 10-15 l of 62% H2SO4 to remove by-products, the oil layer loses its blue color, and the required substances are in the sulfuric acid layer. The last one was shaken with ice and NaOH. As a result, about 7% sodium sulfate solution was obtained. Dilute it to obtain lotion from azulene, extract with 10 L vaseline and distill. 7-isopropyl-1,4-dimethyl azulene was distilled at 167 ° – 168 ° C / 12 mm. The yield is 10-15%.
