溴乙酸叔丁酯——俗名溴醋酸叔丁酯 ，液体；沸 点164℃/100kPa ;不溶于水，溶于乙醇、乙醚等多数有机溶剂。 tert-Butyl bromoacetate - commonly known as tert-butyl bromoacetate, liquid; boiling point 164 °C/100kPa; Insoluble in water, soluble in most organic solvents such as ethanol and ether. （工程上一般用公斤力来表示压力，简称为公斤。换算关系如下：1kgf (1kg) ＝ 100000Pa ＝ 100 kPa ＝ 0．1 MPa。千帕，物理学名词，表示压力为1000Pa。） (Engineering generally uses kilogram force to express pressure, referred to as kilogram.) The conversion relationship is as follows: 1kgf (1kg) = 100000Pa = 100 kPa = 0. 1 MPa。kPa, a physics term, indicates a pressure of 1000 Pa. ） tert-Butyl bromoacetate C6H11BrO2 195.06 国标编号 61617 CAS号 5292-43-3 相对分子量 195.06 折射率：1.444——1.446 折射率，光在真空中的传播速度与光在该介质中的传播速度之比。 材料折射率越高，使入射光发生折射的能力越强。 折射率越高，镜片越薄，即镜片中心厚度相同，相同度数同种材料，折射率高的比折射率低的镜片边缘更薄。 折射率与介质的电磁性质密切相关。根据经典电磁理论，εr和μr分别为介质的相对电容率和相对磁导率。 折射率还与频率有关，称色散现象。光由相对光密介质射向相对光疏介质，且入射角大于临界角，即可发生全反射。 The refractive index, the ratio of the speed at which light travels in a vacuum to the speed at which light travels in that medium. The higher the refractive index of the material, the stronger the ability of the incident light to refract. The higher the refractive index, the thinner the lens, that is, the center thickness of the lens is the same, the same degree of the same material, and the high refractive index is thinner than the edge of the lens with low refractive index. The refractive index is closely related to the electromagnetic properties of the medium. According to classical electromagnetic theory, εr and μr are the relative permittivity and relative permeability of the medium, respectively. The refractive index is also related to frequency, called dispersion phenomenon. Total reflection occurs when light is shot from a relatively light-dense medium to a relatively light-sparse medium, and the angle of incidence is greater than the critical angle. 溴乙酸叔丁酯生产发方法：以溴乙酸与氯化亚砜反应制备并分离得到溴乙酰氯，然后使其与叔丁醇在常温下反应合成溴乙酸叔丁酯。 Production method of tert-Butyl bromoacetate: Bromoacetic acid is prepared and separated by the reaction of bromoac |
