Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Safety of Crystal violet lactone. Introducing a new discovery about 1552-42-7, Name is Crystal violet lactone
Disclosed is a thermochromic microencapsulated pigment which comprises as four essential components (a) an electron-donating chromatic organic compound, (b) an electron-accepting compound, (c) a reaction medium determining the temperatures at which the color reactions of component (a) with component (b) take place, and (d) a color change temperature regulator, the color change temperature regulator (d) comprising one or more compounds selected from the group consisting of esters, alcohols, ketones, acid amides, hydrocarbons, and fatty acids and having a melting point Y ( C.) satisfying the relationship (X+30) C.<=Y<=200 C., wherein X ( C.) is the melting point of component (c), and the four essential components being microencapsulated. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Crystal violet lactone, you can also check out more blogs about1552-42-7
