Unstable

There is justification for allowing t to increase beyond 1, and in many particular applications this may be desirable. Here a more conservative approach is used to reduce the chance of unstable iterations. [Pg.116]

M.p. — 116-3 C, b.p. —55°C. An unstable poisonous gas (metal arsenide plus acid or arsenic compounds plus Zn plus dil. acid, AsCla plus LiAlH4) which decomposes to As... [Pg.42]

Bucherer reaction Bucherer discovered that the interconversion of 2-naphthol and 2-naphthylamine through the action of alkali and ammonia could be facilitated if the reaction was carried out in the presence of (HSO3]" at about 150 C. This reaction is exceptional for the ease with which an aromatic C —OH bond is broken. It is not of general application, it is probable that the reaction depends upon the addition of [HSO3]" to the normally unstable keto-form of 2-naphthol, and subsequent displacement of —OH by —NH2. [Pg.69]

An unstable lower oxidation stale is found in Cd - CdCl and Cd - CdCl - AICI3 melts and may contain Cd — Cd bonds. The common co-ordination number for Cd is 6 (octahedral) although 4 and 5 co-ordination are known. [Pg.74]

Dichlorine tetroxide, CIOCIO3, chlorine perchlorate (CSCIO4 plus chlorine fluorosul-phate, CIOSO2F) diehlorine hexoxide, CliO, oily red liquid (ozone plus CIO2). Both unstable. [Pg.93]

CH2CI-CO-CH3. Colourless lachrymatory liquid b.p. 119°C. Manufactured by treating propanone with bleaching powder or chlorine. It is used as a tear gas and is usually mixed with the more potent bromoacetone. chloro acids Complex chloroanions are formed by most elements of the periodic table by solution of oxides or chlorides in concentrated hydrochloric acid. Potassium salts are precipitated from solution when potassium chloride is added to a solution of the chloro acid, the free acids are generally unstable. [Pg.93]

Chromium hexafiuoride, CrF. Yellow unstable compound (CrF3 plus F2 at high temperatures and pressure). [Pg.98]

CflHaOa. An unstable acid which spontaneously forms a -lactone, coumarin, when the free acid is generated from its salts. See coumaric acid. [Pg.114]

HSCH -CHNHj-COjH. Cysteine is a reduction product of cystine. It is the first step in the breakdown of cystine in the body, one molecule of cystine splitting to give two molecules of cysteine. Cysteine is soluble in water but the solution is unstable, and is reoxidized to cystine. [Pg.124]

The parent acid is unstable and always reverts to the lactone form shown. It is reconverted to acetoacetic ester by boiling alcoholic potassium hydroxide. Reduced by hydrogen iodide to dimethylpyrone. [Pg.127]

These are unstable and known only in solution. The ethyl glucosides can be obtained crystalline and other derivatives are known. [Pg.191]

The naturally occurring isomer, a-licanic acid, has m.p. 74-75" C. It is unstable, and is readily isomerized to the / -form, m.p. 99-5 C. It occurs in oiticica and other oils which were previously used in the protective-coating industry. [Pg.239]

Nb-alkyls and aryls, e.g. MeNbCL and NbMe, Me2pCH2CH2pMe2) are known although relatively unstable. Cyclopenta-dienyl derivatives (h — C5Hs)2NbX3, (h -CjH5)Nb(CO)4 are relatively stable as is [Nb(CO)6] (NbClj + Na in diglyme + CO (pressure)). Tantalum compounds are very similar. [Pg.275]

Nitrogen trioxide, NO3. Unstable while solid (N2OS plus O3). nitrogen oxyacids... [Pg.278]

Nitrous acid, HNO2. See separate entry. Hyponitric acid, H2N2O3, trioxo di-nitrate(Il). Sodium salt from HjNOH in MeOH with CiHiNOi many complexes are known the free acid is unstable. [Pg.279]
