摘　　要：Through the study on relation between the gas phase basicity of aliphatic alcohol,ether and amine and their four kinds of electron effects:inductive effect,conjugative effect,field effect and polarizability effect,the model of gas phase basicity for aliphatic alcohol,ether and amine was described as following:PA(kJ/mol)=2535.1431+316.4274∑I+523.9595PEI-802.6512X_i-544.5804Q_x-9328.6803∑I/PEI+5048.4806∑I/X_i-1070.5125 PEI/X_i.The result of regression analysis showed that the above equation is a good expression for the varying rule of the gas phase basicity of aliphatic alcohol,ehter,and amine.It can provide a relatively reliable model to calculate and predict accurately gas phase basicity for aliphatic alcohol,ether and amine.Through the study on relation between the gas phase basicity of aliphatic alcohol,ether and amine and their four kinds of electron effects：inductive effect, coujugative effect, field effect and polarizability effect, the model of gas phase basicity for aliphatic alcohol, ether and amine was described as following： PA（kJ/mol）=2535,1431＋316.4274∑I＋523.9595PEI-802.6512Xi-544.5804QI-9328.6803∑I/PEI＋5048.4806∑I/Xi-1070.5125PEI/Xi. The result of regression analysis showed that the above equation is a good expression for the varying rule of the gas phase basicity of aliphatic alcohol,ehter,and amine. It can provide a relatively reliable model to calculate and predict accurately gas phase basiclty for aliphatic alcohol,ether and amine.
