4-methyl-2-pentanol conductivity

Immobilized enzymes have been used for years in the preparation of fine chemicals. Racemic amines were resolved by enzyme-mediated acylation (Figure 13.13) [24]. Solutions of the racemic amine 13 and the ester 14 were combined just before being pumped onto the top of a column packed with the enzyme immobilized on glass beads. The nonenzymatic acylation was slowed down by decreasing the contact time of 13 and 14, and by conducting the reaction in 3-methyl-3-pentanol. The eluant was drained directly into concentrated HC1 in order to convert the unreacted amine into the hydrochloride salt 15 and prevent any further nonenzymatic acylation. 

An extensive study of the electrochemistry of ferrocene, methyl viologen, and ferricyanide was conducted in SDS-dodecane-l-pentanol-0.1 M NaCl microemulsion [69]. The ferricyanide was confined to the aqueous phase, while the methyl viologen was partitioned. The shifts in the half-wave potentials were analyzed in terms of the model of Ohsawa et al. [70]. Mackay and coworkers [71-75] investigated microemulsions as media for the degradation of the nerve agent simulant / -nitrophenyldiphenyl phosphate (PNDP) using iodosobenzoate as catalyst. Luminescence and electrochemical studies were conducted in SDS, CTAB, and cetyltrimethylammonoum chloride (CTAC) microemulsions used... 

The atmospheric lifetime of 2,4-dimethyl-2-pentanol with respect to reaction with OH radicals is estimated to be 10 h using [OH] = 2.5 x 10 molecule cm and the rate coefficient presented in this section. The product study conducted by Atkinson and Aschmann (1995) using GC-FK) and GC-MS showed that the reaction of OH with 2,4-dimethyl-2-pentanol gives the following products (molar yields) Acetone (92 15%), 2-methylpropanal (21 22%), 4-methyl-2-pentanone (5 1%), and 4-hydroxy-4-methyl-2-pentanone (12 2%). In addition, the yield of a tertiary nitrate was estimated to be 4 1%.
