The present invention relates to apparatus and methods for making a peroxycarboxylic acid. The apparatus includes a reaction catalyst and a guard column for pretreating one or more reagents, which can increase the life, activity, and/or safety of the reaction catalyst. The peroxycarboxylic acid compositions made by the method and apparatus can include one or more peroxycarboxylic acids.

The invention includes a process for manufacturing an improved solid cast alkaline composition, that includes (a) reacting an alkali metal silicate with an alkali metal hydroxide of the formula MOH, where M is an alkali metal, in an aqueous environment to form a reaction product; and (b) solidifying the reaction product in a mold where the reaction product is formed and solidified at room temperature without the addition of externally supplied heat and the reaction product solidifies without the use of external cooling; and where the relative amount of alkali metal silicate, alkali metal hydroxide and water incorporated into the composition are effective for producing a reaction product having about 20 to 50 parts water per 100 parts of a combination of the alkali metal silicate, the alkali metal hydroxide and water in the cast solid composition and an M O:SiO ratio of about 2.5:1 to 4.0:1 and M is an alkali metal; and where the process does not result in the deactivation of desirable operative cleaning components.
