We report high angular-resolution (~1") CO J=3--2 interferometric mapping,using the Submillimeter Array (SMA), of IRAS22036+5306 (I22036), a bipolarpre-planetary nebula (PPN) with knotty jets discovered in our HST SNAPshotsurvey of young PPNs. In addition, we have obtained supporting lower-resolution(~10") CO and 13CO J=1-0 observations with the Owens Valley Radio Observatory(OVRO) interferometer, as well as optical long-slit echelle spectra at thePalomar Observatory. The CO J=3-2 observations show the presence of a very fast(~220 km/s), highly collimated, massive (0.03 Msun) bipolar outflow with a verylarge scalar momentum (about 10^{39} g cm s^{-1}), and the characteristicspatio-kinematic structure of bow-shocks at the tips of this outflow. TheHalpha line shows an absorption feature blue-shifted from the systemic velocityby ~100 km/s, which most likely arises in neutral interface material betweenthe fast outflow and the dense walls of the bipolar lobes at low latitudes. Thefast outflow in I22036, as in most PPNs, cannot be driven by radiationpressure. We find an unresolved source of submillimeter (and millimeter-wave)continuum emission in I22036, implying a very substantial mass (0.02-0.04 Msun)of large (radius >~1 mm), cold (< ~50 K) dust grains associated with I22036'storoidal waist. We also find that the 13C/12C ratio in I22036 is very high(0.16), close to the maximum value achieved in equilibrium CNO-nucleosynthesis(0.33). The combination of the high circumstellar mass (i.e., in the extendeddust shell and the torus) and the high 13C/12C ratio in I22036 provides strongsupport for this object having evolved from a massive (>~4 Msun) progenitor inwhich hot-bottom-burning has occurred.Comment: to be published in the Astrophysical Journal, 2006, Dec 20, vol 653  23 Pages Text + 8 figures (4 Color
