4-methyl-2-pentanol viscosity

Diocetone Diacetone Alcohol 4-Hydroxy-4-methyl-pentonone-2 or 4-Hydroxy-2-keto-4-methylpentone [called Diacetonalkohol Dimethyl-acetonyl-carbinol 2-Methyl-pentanol-(2)-on-(4) or Methyl-(j8-oxy-isobutyl)-keton in Ger], CH3C0CH2C(CH3)20H mwll6,l6, col, pleasant-odored liq fr p -42.8°, bp 169° at 760mm, flash p 170°F, d 0.9406 at 20°, vapor pressure 1,1mm at 20°, viscosity 0,032 poise at 20°, n 1.42416 at 20°, coeff of expansion 0,00097 at 20. Diacetone is derived by condensation of acetone. It is miscible with alcohols, aromatic halogenated hydrocarbons, esters water. A const boiling mixt with water has a bp 99 6° and contains approx 13% diacetone (Refs 1, 3, 4 5)...
