Any thoughts on the following -

Two pulls with shellite, one with xylene, mix the two together then salt out. 

Would mixing the shellite and xylene cause an issue with the salting?  As far as my thinking goes there should be no problems but a chemist might know more.  Think I'll give this a shot next time.

I don't want to evap the xylene as this will result in dmt oxide in my climate.

The other option is to just extract with xylene and salt out.  How many pulls would I need?

Thanks for any ideas on this.
