For gold balsam, the suitable sulfur balsam which is made of lavender oil and sulfur is found to be the distillate with the content of 15~19% sulfur. The sulfur balsam is distillated under 20mmHg vaccum at 84~105$^{\circ}C$. The composition of the compound which is produced by reaction between sulfur balsam and gold chloride is recognized as C10H18SAuCl3. This varys to C10H18SAuCl in water. The reaction constants K from C10H18SAuCl3 to C10H18SAuCl at 30, 40, 5$0^{\circ}C$ are as followsr. K1=7.97~9.28$\times$10-2 K2=2.81~3.79$\times$10-1 K3=4.74~6.74$\times$10-1 The plots of T versus log K are linear, which shows pseudo-first order reaction. The lower temperature is, the more stable C10H18SAuCl3 is. The gold balsam with excess sulfur balsam is increased in stability.
