折光率（2%水溶液,20℃）        1.336

                                   PH                                            5.5 - 7

                    冰点（℃）                                0

                    色标（铂-钴色标）                      40

                    25℃、1%水溶液

                    表面张力N/W                             0.06--0.065

                    表观粘度（AV,厘泊）       122

    注：表观粘度（AV）是用XT-40，40000cp的HEC配成1.2%水溶液在25℃用范氏粘度计测定，AV值是在600rpm时仪器读数的1/2。
