Kelarutan Methyl Red dan Methylen Blue dalam Gelasi Mikroemulsi Water in Oil Sistem dari Air, Triton X-100 dan Sikloheksana Serta Aplikasinya Untuk Tinta Ballpoint

Sari

The solubility of methyl red and methylene blue in the gelation of water in oil
microemulsion of the system of water (pH=4,0 dan pH= 9,5),Triton X-100, cyclohexane
and its application for ballpoint ink. To get the stable red colour of methyl red we used the
water pH 4,0 (controlled by nitric acid) and to get the stable blue colour of methylen blue,
we used the water pH of 9,5 (controlled by potassium hydroxide), the formation of gel from
water in oil microemulsion was crieddent using the sol-gel method by
Tetraethylorthosilicate (TEOS) which underwent hydrolysis with water to form a gel. It
was indicated that the solubility of methyl red and methylen blue The gelation of water in
oil microemulsion were 1.6820 gram and 1,7260 gram.
