Insight Into

This chapter analyses how Russian courts have approached principles and standards of the Convention on the Rights of Persons with Disabilities (CRPD) since its ratification by Russia in 2012. Given the monist features of the Russian legal system, the Convention has been used in a relatively large number of judgments. In the majority of cases the CRPD has been used only to reinforce the standards already provided by domestic laws. In a few cases, however, judges interpreted the Convention provisions to establish new legal concepts or to apply progressively Russian laws concerning human rights of people with disabilities. The chapter provides a critical insight into different ways of interpreting (or failing to interpret) CRPD provisions used by Russian courts and it concludes that the impact of the CRPD on case law has so far been limited despite its implementation in the Russian legal system.

Azo Derivatives

The synthesis of azo compounds from eugenol has been carried out by diazotation reaction. The diazonium salt was produced by reaction of aniline and sodium nitrite in acid condition at 0-5 °C temperature to yield benzenediazonium chloride salt. The salt was then reacted with eugenol to produce the azo derivatives. The azo product was analyzed by IR, 1H-NMR, dan GC-MS spectrometer. The results showed that the reaction of benzenediazonium chloride with eugenol gave 4-allyl-2-methoxy-6-hydroxyazobenzene in 34.27% yield for 30 minutes reaction. The derivative of azo compound was dissolved in ethanol and then the color changing was observed in range of pH 9.8-11.1 from yellow to red. Application for titration indicator for acetic acid titrated with sodium hydroxide showed error less than 3.20% compared with phenol phtaline indicator.   Keywords: Eugenol, Azo compound, titration indicator
