测定不同碳链脂肪醇硫酸钠的物化性能,如表面张力、cmc值、乳化、接触角、耐硬水性和泡沫等。结果表明,C12～14醇硫酸钠降低表面张力的效果最佳。随着烷基碳链变长,脂肪醇硫酸钠的接触角变大且耐硬水性能也变差。C8～10醇硫酸钠的发泡力最差,且C16～18醇硫酸钠因其耐硬水性能差,其发泡力随着水硬度的增加而下降。以C16～18醇硫酸钠的乳化性能最好。

The chemical properties of sodium fatty alcohol sulfate with different carbon chains,such as surface tension,cmc,emulsification,contact angle,resistance to hard water,foaming power,etc.were determined.The results illustrated the longer carbon chain,the bigger contact angle and the poorer resistance to hard water.The sodium C12～14 alcohol sulfate showed the best property in reduction of surface tension.The sodium C8~10 alcohol sulfate showed the worst foaming property.The foam of sodium C16~18 alcohol sulfate decreased with the increasing hardness of water due to its bad resistance to hard water.The sodium C16～18 alcohol sulfate showed the best emulsifying performance.
