    Abstract: A process for preparing an organometallic framework material comprising reacting at least one metal salt with at least one at least bidentate compound capable of coordination to the metal ion of said metal salt, in the presence of an aqueous solvent system and at least one base wherein at least one bidentate compound comprises at least carboxy group and at least one further group which is not a carboxy group and which is capable of forming a hydrogen bridge linkage.

    Abstract: Composition (A) contains at least one alkoxylated 6-18C alkanol (I). Composition (A) contains at least one alkoxylated 6-18C alkanol of formula RO-(A)n-(B)m-H (I). R = 6-18C linear or branched alkyl; A = propyleneoxy (PO); B = ethyleneoxy (EO) or a mixture of EO and PO; n = integer or fractional number of 0-5; and m = integer or fractional number of 0-20. When R is C5H11CH(C3H7)CH2-, n is less than 1, provided that R is a mixture where 70-99 %, by weight of C5H11 is linear and 1-30 %, by weight is EtCH(Me)CH2 and/or MeCH(Me)CH-2CH2. An Independent claim is also included for a method for preparing (I) by reacting ROH with propylene and ethylene oxides.

    Abstract: A process for preparing polyether polyols includes a precipitation step, a recrystallization step, and a reaction step. In the precipitation step, a multimetal cyanide compound is precipitated by reaction of a metal salt with a cyanometalate compound. In the recrystallization step, the multimetal cyanide compound precipitated above is recrystallized by adding further metal salt and/or further cyanometalate compound. The recrystallization forms a multimetal cyanide catalyst compound. In the reaction step, an initiator and one or more alkylene oxide are reacted in the presence of the multimetal cyanide catalyst compound.
