It is a colorless liquid. Synthesis 2,2-Dichloropropane can be synthesized by reaction between acetone and phosphorus pentachloride at low temperatures.Preparation of 2,2-dichloropropane https://www.prepchem.com/synthesis-of-2-2-dichloropropane/ CH3\sCO\sCH3 + PCl5 → CH3\sCCl2\sCH3 + POCl3 Another method involves the reaction between 2-chloropropylene (CH3\sCCl\dCH2) with hydrogen chloride.https://patents.google.com/patent/EP0665202A2/en CH3\sCCl\dCH2 + HCl → CH3\sCCl2\sCH3 Structure The distances and angles between atoms in 2,2-dichloropropane molecule are as follows:Hirota Masashi Iijima Takao Kimura Masao Molecular Structure of 2,2-Dichloropropane as Determined by a Combined Use of the Electron-diffraction Data and the Spectroscopic Moments of Inertia Bulletin of the Chemical Society of Japan 1 June 1978 51 6 1589–1593 10.1246/bcsj.51.1589 https://academic.oup.com/bcsj/article-abstract/51/6/1589/7356872 subscription d(C-H) = 111 pm d(C-Cl) = 179.9 pm d(C-C) = 152.3 pm ∠(Cl-C-Cl) = 108.3° ∠(C-C-C) = 113.0° The C-Cl and C-C distances are shorter than the corresponding distances in 2-chloropropane. Polymorphism of 2,2-dichloropropane The polymorphism of 2,2-dichloropropane has been investigated by thermal and X-ray powder diffraction experiments. From the former the phase transitions between the different phases have been characterized at normal and high pressures (up to 200 MPa). The existence of two low-temperature stable ordered phases (II and III), one high-temperature orientationally disordered phase (rhombohedral, Ib) and one additional monotropic orientationally disordered phase Ia, has been confirmed. The structure of the low-temperature ordered phase II has been determined by X-ray powder diffraction and Rietveld refinement as monoclinic C2/c, with lattice parameters a = 10.6402(3) Å, b = 5.4074(2) Å, c = 10.7295(3) Å, and β = 116.274(3)° at 175.2 K C F.Negrier P.

It is highly flammable. Its vapors form explosive mixtures with air. While burning, it releases toxic gases including carbon monoxide, carbon dioxide, and hydrogen chloride. It should not be allowed to enter drains due to the risk of explosion. This chemical poses acute and chronic health hazards. It is harmful if inhaled. Can cause serious eye irritation. It is a neurotoxin and hepatotoxin. References Category:Organochlorides
