Abstract
The product is presented in the form of a solution and is composed of carbonated magnesium di-n-propylate, n-propanol, and a hydrofluorocarbon (HFC) diluent selected from 1,1,1,2-tetrafluoroethane (HFC 134a) and 1,1,1,2,3,3,3-heptafluoropropane (HFC 227). The product may be obtained by a procedure which comprises preparing a solution of carbonated magnesium di-n-propylate in n-propanol and diluting said solution by addition of the HFC diluent. The product is suitable for de-acidifying cellulose-type material and preserving objects based on cellulose-type material.
