Paper Title:
Trisiloxane Surfactants Technology Optimization and Impact of Surface Tension
  Abstract

Trisiloxane surfactants can significantly enhance the biological activity of pesticides, in order to optimize of synthesis technology,in this paper,there was no gas protection,cleared trisiloxane surfactants optimization conditions by took the sample at different reaction time and measured degree of reaction degree by chemical titration method,infrared spectroscopy characterized,deteminated surface tension and controled weeds. This technology is more convenient than existent technology.The best reaction conditions:catalyst was 10mg/L,reaction temperature was 80 ,material ratio was 1:1.2, reaction time was 5 hours,the degree of their response would totally up to 93.83%.The surface tension compared with Silwet408 no significant difference to water and liquid. Different reaction degree trisiloxane surfactant could increased weed control of fomesafen differently.When added reaction degree 93% trisiloxane surfactant,dosage 1‰((v/v),enhanced observing 28.5% and fresh weight 29.5% than 252g ai/hm-2 only treated.Thus,this method could be used in production of trisiloxane surfactants.
