The development of modern skin flap chirurgery needs badly the three- dimension picture system to display the blood supply and other profound structures and functions. This kind of system can also support the clinical training, designing of operative route, suppositional operation procedure and fidelity navigation during the operation. 3D imaging studies such as computed tomography and magnetic resonance provide the primary source of patient-specific data for such medical applications. The two-dimensional (2D) images produced by CT and MR imaging techniques represent a series of cross-sectional image slices through ones anatomy.

First, a chlorinator was self-designed in this paper, and dichloride of 2-methyl-1-propene was synthesized by 2-methyl-1-propene reacted with chlorine fast in this reactor. By means of the Orthogonal Experiments design and single factor experiments, the influence of several reaction variables on the yield were examined and the optimum reaction conditions under the intervallic operation were obtained, the yield and selectivity of dichloride of 2-methyl-1-prop-ene were more than 65% and 80% respectively. Second, the preparation of 2-methylene-1, 3-propanediol, which dichloride of 2-methyl-1-propene reacted with alkali was investigated. By means of the Orthogonal Experiments design and single factor experiments, the influence of several reaction variables on the yield were examined and the optimum reaction conditions under the intervallic operation were obtained, the conversion of dichloride of 2-methyl-1-propene was 100%. Moreover the preparation of MPO, which 2-methylene-1, 3-propanediol reacted with hydrogen, in presence of Al_2O_3-Pd catalyst, was gotten, and the product was appraised.

本文在氯化反应过程中，自行设计制作出了氯化管式反应器，在该反应器中异丁烯和氯气迅速混合反应生成二氯异丁烯，根据该氯化反应特征利用正交试验和单因素试验考察了有关因素的影响并优化得到了最佳工艺条件，二氯异丁烯的总收率达65％以上，选择性达80％；接着，对二氯异丁烯进行水解反应制得了2-甲烯-1，3-丙二醇，讨论了相关因素对水解反应的影响，并通过正交试验和单因素试验得到了较佳工艺条件，二氯异丁烯的转化率达100％；同时还对制备的2-甲烯-1，3-丙二醇在常压下采用三氧化二铝负载钯催化剂催化加氢得目的产物MPO，并对产品进行了鉴定，从而打通了整个工艺路线。
