Synthesis and surface-active property of bis-quaternary ammonium-sodium sulfate Gemini surfactant
      
N,N-dimethyldodecylamine, hydrochloride and epichlorohydrin (molar ration is 2:1:1) were used to synthesize bis-quaternary ammonium Gemini surfactant with a hydroxyl in its spacer group by the one-pot method.
      
This hydroxyl was sulfonated by chlorosulfonic acid and then neutralized to bis-quaternary ammonium-sodium sulfate zwitterionic Gemini surfactant.
      
The critical micelle concentration (cmc) and surface tension of the novel zwitterionic Gemini surfactant in aqueous solution at 15°C are 7.2×10-5 mol/L and 34.5 mN/m, respectively.

When the milk contains more leucocytes, precipitates or gel are observed. Through 1,170 milk samples of parallel test with CMT and HMT respectively, the diagnostic effect of HMT is very similar to CMT, Therefore HMT is useful for detecting mastitis milk in dairy cows.

本文主要阐述杭州奶牛乳房炎诊断液(HMT)的研制方法。该诊断液是采用一种阴离子表面活性剂—烷基硫酸钠为主要原料配制而成。HMT与CMT(加州乳房炎试剂)的作用机理相同,但所用表面活性剂不同.HMT与奶汁细胞中的DNA相作用而产生沉淀或凝胶,可间接判定其细胞的增数范围而达到诊断目的。通过HMT与CMT对1170个乳区奶样的对比试验,其结果基本一致,因而HMT作为一种奶牛乳房炎的诊断液,可推广使用.

This paper makes a research into the photometric analysis for direcily delecting, in water phase and without resort to enrichment and separation, the trace element Zn in grain. Sodium citrate, sodium metaphosphate and copper reagent are introduced in a combined way to screen interfering ions in the grain. With the existence of sodium lauryl sulfate, a surfactant of negative ions, Zinc and 5-Br-PADAP combine to form a red kind of soluble complex. The color of this complex will last for 8 hours at least and its molai absorptivity ε - 1.4 × 105lit ·mol-1 ·cm-1. The content of 0-10 micrograms of Zn in 25 ml of the solution is desirably in conformity with Beer-Lambert Law. The result of the analysis of the trace element Zn in soya bean, maize, rice and wheat is satisfactorily tested and verified by means of a standard addition method,with a coefficient of variation less than 1.2% and a recovery ratio between 94 and 104%
