Basicity Factors of Limestone and Lime

Abstract

crop plants for the mineral nutrients present. It should also contribute to the formation of humus, since most of the humus found in soils results from a combination of lignin with bacterial proteins.

Lime Treatment of Waste Pickle Liquor

“…In general, sludges produced by' quicklimes settle faster than those from hydrates, and high calcium sludges faster than dolomitic. It was shown previously (1) that the settling rate of sludges will be approximately the same as the settling rate of the lime suspended in water. There is no explanation for the curious behavior of the sludge from sample 6, which settled considerably faster than either of the limes from which it was compounded.…”

“…The narrow explosive range of methanol, however, coupled with the fact that all of the operating units are enclosed, precludes the possibility of a combustible level being reached in the atmosphere. In addition, safety valves and alarms are dispersed throughout the first paper in this series described rapid analytical methods for determining the available alkalinity of limes and limestones and the total sulfate ion in waste pickle liquor (1). The second article discussed certain factors having economic importance where high-calcium limes and limestones are used to treat such waste liquors (£).…”

“…Chemical analysis of complex alkaline substances is time-consuming and generally will reveal little about their reactivity or available basicity. Basicity factors (11), determined under conditions simulating the actual neutralization, provide both an accurate measure of available basicity and considerable information about reaction rate. They are expressed as grams of equivalent calcium oxide per gram of substance, regardless of the composition of the alkaline material.…”

Pickle Liquor Neutralization

“…A condensed summary of the reactivities of certain common agents is given in Table II. Reactivities were compared under four reaction conditions: (1) room temperature, no aeration; (2) 60°no aeration: (3) room temperature, with aeration; and (4) 60°C ., with aeration.…”
