Claims
- 1. A crystalline adduct consisting essentially of MgCl.sub.2 complexed with an electron donor selected from the group consisting of an alcohol and a phenol in an equal molar ratio, such that said crystalline adduct has the sharp x-ray diffraction spectrum peaks associated with crystalline materials, said spectrum being characterized by the absence of the peak which normal crystalline MgCl.sub.2 has at 2.theta.=15.degree. and the absence of any substantial peaks in the 2.theta. range of 45.degree.-55.degree..
- 2. A crystalline adduct according to claim 1 consisting essentially of MgCl.sub.2.CH.sub.3 OH having the sharp x-ray diffraction spectrum peaks associated with crystalline materials, said spectrum being characterized by the absence of the peak which normal crystalline MgCl.sub.2 has at 15.degree. to 2.theta., the presence of a peak at 2.theta.=12.degree., and the absence of any substantial peaks in the 2.theta. range of 45.degree.-55.degree..
- 3. A method for preparing said crystalline adduct of claim 2 which comprises pulverizing anhydrous MgCl.sub.2 and MgCl.sub.2.6CH.sub.3 OH at a temperature in the range of about 0.degree. C. to about 100.degree. C. for a time period in the range of about 1 hour to about 10 days.
- 4. A method for preparing said crystalline adduct of claim 1 which comprises pulverizing anhydrous MgCl.sub.2 and said electron donor selected from the group consisting of an alcohol and phenol at a temperature in the range of about 0.degree. C. to about 100.degree. C. for a time period in the range of about 1 hour to about 10 days.
- 5. A method according to claim 3 wherein said pulverizing is conducted at a temperature in the range of about 20.degree. C. to about 50.degree. C.
- 6. A method according to claim 4 wherein said pulverizing is carried out for a period of about 2 hours to about 2 days.
- 7. A method for preparing a crystalline adduct consisting essentially of MgCl.sub.2.CH.sub.3 OH having the sharp x-ray diffraction spectrum peaks associated with crystalline materials, said spectrum being characterized by the absence of the peak which normal crystalline MgCl.sub.2 has at 2.theta.=15.degree., the presence of a peak at 2.theta.=12.degree., and the absence of any substantial peaks in the 2.theta. range of 45.degree.-55.degree.; wherein said method comprises pulverizing anhydrous MgCl.sub.2 and MgCl.sub.2.6CH.sub.3 OH, wherein said pulverizing is carried out at a temperature in the range of 25.degree.-30.degree. C. for a period of 4-16 hours.
- 8. A method according to claim 4 wherein said electron donor is a phenol.
- 9. A method according to claim 8 wherein said pulverizing is conducted at a temperature in the range of about 70.degree. C. to about 90.degree. C.
- 10. A method according to claim 9 wherein said pulverizing is carried out for a period of about 4-24 hours.
- 11. A crystalline adduct prepared by the method of claim 9 which consists essentially of MgCl.sub.2.phenol.
- 12. A crystalline adduct prepared by the method of claim 9 which consists essentially of MgCl.sub.2.4-phenyl phenol.
