Drug Information
Chemicals and substances that impart color including soluble dyes and insoluble pigments. They are used in INKS; PAINTS; and as INDICATORS AND REAGENTS. (See all compounds classified as Coloring Agents.)|Substances used in the processing or storage of foods or animal feed including ANTIOXIDANTS; FOOD PRESERVATIVES; FOOD COLORING AGENTS; FLAVORING AGENTS; ANTI-INFECTIVE AGENTS; EXCIPIENTS and other similarly used substances. Many of the same substances are used as PHARMACEUTIC AIDS. (See all compounds classified as Food Additives.)|Chemicals that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags. (See all compounds classified as Fluorescent Dyes.)

C.I. Solvent Green 7 Use and Manufacturing
In 2000 ml three-necked flask into 1200 grams of concentrated sulfuric acid, stirring into the 120 grams of flowers, a little warming to promoteAfter all the dissolved, slowly warming to 90 ° C for 1 hour, three bottles with a water bath to cool below 40 ° C, drop the liquid sulfur black 480 grams, 3 hours drop finished. And then to maintain the temperature of about 100 ° C reaction for 5 hours, down to room temperature, the three bottles of material into the 720 grams of ice water, into a sticky material, filter dry filter cake, get pyrene tetrasulfonic acid tetrasodium salt. And then the pyrene tetrasulfonic acid tetrasodium salt dissolved in 1000 ml of water into the 2000 ml three-necked flask, stirring with a plate of sodium hydroxide to neutral, then add 300 grams of flaky sodium hydroxide, slowly warming To micro-boiling state for 5 hours. After cooling, the first with hydrochloric acid and PH value of 7 or so, then add 100 grams of sodium chloride stirring dissolved, slowly precipitated light yellow solid, filtered and dried to get 8-hydroxy-1, 3, 6-pyrene three Sodium sulfonate salt about 245 grams.In 2000 ml three-necked flask into 1200 grams of concentrated sulfuric acid, stirring into the 120 grams of flowers, a little warming to promoteAfter all the dissolved, slowly warming to 90 ° C for 1 hour, three bottles with a water bath to cool below 40 ° C, drop the liquid sulfur black 480 grams, 3 hours drop finished.
