Based on the conditions that product P can be attained (WT %(alkali):40%, 40 ¡æ, 6 h,MR(CTA to ¦Â-chintin) :4),other factors is in the same level, change Alkali concentration,temperature,reaction time and volume of CTA seperately. When the alkali concentration is high,the solubility of CTA can be reduced,and the formation rate of byproduct(Bibol) from the hydrolysis of partly-existing GTMAC greatly increased |

The reaction condition was set on the basis of the desired condition of sample P (40 wt %, 40 ¡æ, 6 h, 4), and then changing an individual factor. At high alkaline concentration, the solubility of CTA is reduced and the hydrolysis of the diol withpartial epoxide is increased. |

| Take the good product P response condition (alkali quantity percentage density 40%, temperature 40¡æ, reaction time 6h, CTA with Beta - carapace element unit mole compared to as 4) is a datum, fixes other factors to change the caustic concentration, the temperature, the reaction time and CTA separately joins the quantity. |
