This f'aot is sufficient reason for the study here described. In some cases, espeoially among terpen.es, the compounds formed by adding NOCl, 1203 , or »2o4 at one or more of the double bonds have been used as derivatives but these are i nconvenient to make,. of un certain composition, and decidedly unstable! This work con- '\, sists of (l) a'ttempts to find a convenient samll scale meth- od for adding (S0N)2 to olef1ns, (2) the determinations of the melting points of the derivatives, and (3) quantitatiye analysis of derivatives to prove their structure and purity. -

Akademika Lavrentyeva 3, Novosibirsk 630090 (Russia) (Received April 21, 2003; in revised form January 6, 2004) Abstract Processes that occur during extraction of cyanides from cyanidation solutions using centrifugal bubbling apparatuses (CBA) as reactors have been studied. In the eddy chamber of CBA (ðÍ < 3), one can observe virtually complete removal of HCN from solution and precipitation of heavy metals in the form of insoluble x - 1 compounds. The electronic absorption spectra of solutions treated in CBA suggest that destruction of [Cu(CN)x] , + 2+ 2 oxidation of Cu to Cu by air oxygen, and oxidation of thiocyanates in the presence of SO23, forming 2 HCN and SO4 , are also accompanied by the emergence of stable intermediate products (SCN)2 and (SCN)x of oxidation in solution.

VII. PUBLICATIONS (APRIL 2011 – MARCH 2012) VII. PUBLICATIONS Since 1967, the institute published the Annual Report of the KURRI, containing the original papers written by researchers of the institute and users of other organizations. It played an important role in showing the activities of the institute. However, due to a variety of research fields covered by researchers in the institute, it became difficult to contain all the original papers. Therefore, the Annual Report was discontinued in 1995. The Progress Report of the KURRI has been issued from 1991 in English and summarizes the abstracts of the published papers, reviews, book titles and current research activities of the KURRI. The Technical Report of the KURRI (KURRI-TR) has been issued occasionally from 1965. It contains technical data in Japanese with English summaries. The KUR Report (KURRI-KR), issued in Japanese since 1996, is the proceedings of symposia and technical meetings held at the institute. Furthermore, the CD-ROM version (KURRI-KR(CD)) has been issued from 2004.
