- n. (Chem.) An acetate containing an excess of the basic constituent.
Examples
“The glycerol content is ascertained by taking 2.5 grammes, adding lead subacetate solution, and filtering without increasing the bulk more than is absolutely necessary; the solution is concentrated to about 25 c.c., and the oxidation with bichromate and sulphuric acid conducted as described in the examination of Crude Glycerine.”
“In such case, before making up to the mark, a saturated solution of subacetate of lead is added.”
“If the proper amount has been added, the precipitate will usually subside rapidly, but if not, the operator may judge of the completeness of the precipitation by holding the flask above the level of the eye and allowing an additional drop of subacetate of lead to flow down the side of the flask into the solution; if this drop leaves”
“After adding the solution of subacetate of lead the flask must be gently shaken, so as to mix it with the sugar solution.”
“The use of subacetate of lead should, in all cases, be followed by the addition of "alumina cream" (aluminic hydrate suspended in water) [2] in about double the volume of the subacetate solution used, for the purpose of completing the clarification, precipitating excess of lead, and facilitating filtration.”
“The operator must learn by experience the point where the addition should cease; a decided excess of subacetate of lead solution should never be used.”
“Excess of subacetate of lead solution in clarification.”
“In many cases of high grade sugars, especially beet sugars, the use of alumina alone will be sufficient for clarification without the previous addition of subacetate of lead.”
“Take of lard 1 oz., solution of subacetate of lead 25 drops, tinc. of opium 1 drm.; mix well.”
“Take of lard 7-1/2 drms., creosote 10 drops, solution of subacetate of lead 10 drops, watery extract of opium 1 grain; mix.”
