Dimethylvaleric acid

As in the case of the linear carboxylic acids, the principal by-products are water, C02 and the corresponding hydrocarbons. Substantial quantities of iso-butane are formed for example during iso-butyric acid homologation (see Experimental Section) while 2-methylpentane accompanies the formation of 2,2-dimethylvaleric acid during syngas treatment of 2-methylvaleric acid. [Pg.230]

Gemfibrozil Gemfibrozil, 2,2-dimethyl-5-(2,5-dimethylphenoxy)valeric acid (20.2.4), is synthesized either by hydrolysis of ethyl ester of 2,2-dimethyl-5-(2,5-dimethyl-phenoxy)valeric acid (20.2.3), which is synthesized by alkylation 2,2-dimethylvaleric acid... [Pg.272]

Although camosic acid and carnosol are readily oxidized at 60°C and higher temperatures, their antioxidant activities are maintained. The oxidation products formed are apparently active antioxidants at high temperatures and protect oils during frying. They also have carry-over activity by protecting the fried foods. This carry-over activity can be attributed to the formation of various oxidation and isomerization products. Indeed, the radical [2,2 -azobis-(2,4-dimethylvalerate)] initiated or iron-catalysed oxidation of camosic acid in the... [Pg.239]
