10-methyl- -perchlorate

This method is exemplified by its application to quinoline, isoquinoline, cinnoline, and isoquinoline 2-oxide, which are nitrated as their conjugate acids. The rate profiles for these compounds and their N- or O-methyl perchlorates show closely parallel dependences upon acidity (fig. 2.4). Quaternisation had in each case only a small effect upon the rate, making the criterion a very reliable one. It has the additional advantage of being applicable at any temperature for which kinetic measurements can be made (table 8.1, sections B and D). 

A lipid was extracted from a methanol/chloroform mixture, the solution obtained was then treated with 1.5 cm of 72% perchloric acid. This led to a violent detonation, which was explained by the decomposition of methyl perchlorate. 

An attempt to dry trimethyl phosphite by using magnesium perchlorate ended with the compounds detonation. This accident was put down to the formation of methyl perchlorate. However, by analogy with a similar accident described in... 

Contact between the salt and ester caused violent explosions on several occasions. (Methyl perchlorate may have been formed).

Oxidation of dihydro-X -phosphorin 147 with triphenyl-methyl-perchlorate leads to an intermediate which most likely has the structure 127. Addition of phenyl-lithium to this cation affords the deep red 1,1,2,4,6-pentaphenyl-X -phosphorin... 

It was first prepd by treating xanthydrol with perchloric add in eth (Ref 3) or nitrobenzene (Ref 2). It has also been prepd by the oxidation of xanthene with triphenyl methyl perchlorate, and the product recrystd from acet to giver bronze plates (Ref 6) The refs consider the compd to be an expl... 

The explosive properties of these two substances were examined by Berthelot [4]. He found that methyl perchlorate is endothermic substance, with a heat of formation —AZ/f of 4 kcal/mole. 

The explosive decomposition of methyl perchlorate approximately follows the equation ... 

They also found that methyl perchlorate can be formed by the action of diazomethane on perchloric acid. The esters can be hydrolysed by water. The ease of hydrolysis increases from the propyl to the methyl derivative. 

During digestion of a lipid extract (1 mg) with 72% acid (1.5 ml), a violent explosion occurred. This was attributed to residual traces of the extraction solvent (methanol— chloroform) having formed methyl perchlorate [1]. In the analytical determination of potassium as perchlorate, heating the solid containing traces of ethanol and perchloric acid caused a violent explosion [2], Contact of drops of anhydrous perchloric acid and... 

The hexasolvated compound was being prepared from a mixture of the hydrated salt, methanol and dimethyl sulfoxide but inexplicably mercury(I) oxide came out of solution. This was redissolved by addition of perchloric acid and the solution was refrigerated for 60 h. After addition of molecular sieve to remove the water present, the solution was filtered and the sieve treatment repeated four more times. During the final filtration, a violent explosion occurred in the funnel. The most likely cause was formation of methyl perchlorate promoted by the dehydrating action of the sieve, but dimethyl sulfoxide also forms an unstable salt with perchloric acid, so this also may have been involved [1], During preparation of...
