Exhibit 99.1

Albemarle Divests Thann Facility to International Chemical Investors

RICHMOND, Virginia—August 31, 2006—Albemarle Corporation (NYSE: ALB) and International Chemical Investors S.A. (ICIG) have completed the transfer of ownership of Albemarle’s manufacturing facility in Thann, France to ICIG. Under the terms of the agreement, Albemarle has transferred to ICIG 100 percent of the stock of Albemarle France S.A.S. and its subsidiary Albemarle PPC S.A.S., the owner of the facility, together with all related assets and liabilities. At closing, Albemarle PPC changed its name to Potasse et Produits Chimiques S.A.S. (PPC).

PPC is a producer and marketer of potassium, chlorine and other fine chemical products, with approximately 265 employees and 2005 revenues of approximately €110 million.

As part of the transaction, PPC will become the exclusive marketer for Europe of potassium hydroxide products produced by Albemarle’s joint venture in Jordan, and will manufacture certain bromine fine chemical products for Albemarle at the Thann site.

All marketing activities of PPC will be conducted by a newly formed Belgian subsidiary named PPC International S.P.R.L. Alex Smit, who was responsible for the PPC businesses, in addition to other senior functions at Albemarle Europe, has been named Managing Director of all PPC companies.

“We are very pleased that we were able to complete this transaction in a timely fashion. This is a positive step for Thann and for Albemarle’s fine chemicals business,” said John Nicols, Albemarle Vice President, Fine Chemicals.

Albemarle expects to take a pre-tax charge of approximately $90 to $95 million related to this transaction in the third quarter of the current fiscal year. Albemarle’s previously announced consultation process with the works council at Thann to potentially cease operations at this site has been cancelled.
