The invention discloses a preparing method of high boiling silicon oil, which comprises the following parts: óƒ alcoholysis: allocating 100 wt organic silicon high boiling material in still; dipping into 30-40 wt carbinol with mass percent at 80-90% under 20-25 deg.c; dipping at 6-8 h; controlling speed at 3 wt/h at first between 2 h and 3 h; increasing to 10 wt/h than; generating hydrogen chloride gas during alcoholysis course; absorbing with spray water; rising the temperature of still to 60-70 deg.c; stripping alcaine; absorbing hydrogen chloride gas with water; ó… neutralization: adding into 15-18 wt carbinol assisting solvent and same quantity calmuril; neutralizing with alcaine; controlling neutralizing temperature at 42-50 deg.c and time at 0.5 h; getting rough high boiling oil through stratify with pH value at 4-5; adding into 1.0-1.5 wt ammonia with mass percent at 27%; neutralizing till pH = 6-8; filtering; getting end product.
