	Aqueous coating composition - Patent 4071645 (Site not responding. Last check: 2007-11-04)
		Thymolphthalein, phenolphthalein, ortho-cresolphthalein and ethyl bis (2,4-dinitrophenyl) acetate are preferred because they provide a more vivid color which is readily visible when the coating composition is applied to a wider variety of different colored substrates.
		The amount of color indicator used depends primarily upon the specific one selected, the desired degree of coloration of the film during stripping, the original pH of the coating composition and the pH of the cleaning or stripper composition to be used.
		When thymolphthalein is used as the color indicator in the coating composition of this invention, the pH of the cleaning or stripper composition usually should be at least 11.6 so that film will turn a vivid blud color.

		The contents of the mixer are then permitted to cool and the Thymolphthalein (0.4317 lb dissolved in 25.512 lbs of denatured ethanol) is added and the mixture is allowed to cool to room temperature.
		Lastly, the Thymolphthalein (0.574 lb dissolved in 33.905 lbs of denatured ethanol) is added to the mixture and the mixture is allowed to mix for 30 minutes.
		Lastly, the Thymolphthalein (0.587 lb dissolved in 34.684 lbs of denatured ethanol) is added and to the mixture and the mixture is allowed to mix for 5 minutes.

		Roy, et al (2) recommended sodium thymolphthalein monophosphate as a substrate for prostatic acid phosphatase because of the high degree of selectivity shown in the reaction.
		Prostatic acid phosphatase hydrolyzes sodium thymolphthalein monophosphate releasing thymolphthalein.
		Sodium thymolphthalein monophosphate demonstrates a high degree of specificity for the prostatic acid phosphatase and reacts to a much lesser extent with the platelet and erythrocytic acid phosphatases (7).

		Add 2-3 droppers full of thymolphthalein indicator to the ethyl alcohol.
		When the solution is squirted onto the shirt, it reacts with the carbon dioxide in the air.
		The color of the thymolphthalein is colorless in the presence of acid.

		Use phenolphthalein or thymolphthalein indicators and observe how they react with acids or bases.
		Take about one cup of shredded red cabbage, and boil it in two cups of water for five minutes in a nonaluminum pan.
		Make thymolphthalein indicator solution by dissolving 0.1 g thymolphthalein in 50 mL of ethyl alcohol.

		If you must, tell the students that these chemicals are acids and bases, and ask them to group them and order them according to concentration.
		An excellent question is to ask students for a description of the chemical role of thymolphthalein.
		(Thymolphthalein is a pH indicator very much like phenolphthalein except that it turns blue instead of pink in a basic solution.)

		I am hoping someone could offer some help with something i am working on.
		Thymolphthalein should work and I guess it's not much more toxic than phenolphthalein.
