Solubility powders

C22H23N3O9. An organic reagent used for the detection and estimation of aluminium. It is a brownish-red powder, soluble in water which gives a red lake with aluminium which can be estimated colorimetrically. It can also be used for detecting scandium and indium. 

Pectin also contains araban and galactan. Il is present in fruits, root vegetables and other plant products, and confers on jams their typical gelling property. Pectin is manufactured as a white powder, soluble in water, and used to assist the setting of jams and jellies, and for numerous other purposes. Low melhoxyl pectins, with under 7% methoxyl, give firmer gels than pectins proper. 

Sucralfate. Sucralfate [54182-58-0] (Carafate) (6) is a white amorphous powder soluble in dilute hydrochloric acid and sodium hydroxide. It is practically insoluble in water, ethanol, and carbon tetrachloride. Dissolution of aluminum occurs at pH <3. It may be prepared by the method described in Reference 7. 

Lead Sesquioxide. Lead sesquioxide (lead trioxide), Pb202, is an amorphous, orange-yeUow powder soluble ia cold water. It decomposes ia hot water and ia acids to lead salts plus Pb02. Lead sesquioxide can be prepared from lead dioxide by hydrothermal dissociation (43). 

Mercuric Acetate. Mercuric acetate/7ti(9(9-27-7/, Hg(C2H202)2, is a white, water-soluble, crystalline powder, soluble in water and many organic solvents. It is prepared by dissolving mercuric oxide in warm 20% acetic acid. A slight excess of acetic acid is helpful in reducing hydrolysis. 

Calcium Methylate Ethylate and Ethylate. Calcium methoxide [2556-53-8] and ethoxide [2914-17-2], Ca(OCH2)2 and Ca(OC2H )2, are white powders soluble in the corresponding alcohol (max concentration 1%). They are packaged and stored like the magnesium alkoxides.

Napbtboi Yellow S (citronin A, flavianic acid sodium salt, 8-bydroxy-5,7-dinitro-2-napbtbalene sulfonic acid disodium salt) [846-70-8] M 358.2, m dec on beating. Greenish yellow powder soluble in H2O. The/rce sulfonic acid can be recrystd from dil HCl (m 150") or AcOH-EtOAc (m 148-149.5"). The disodium salt is then obtained by dissolving the acid in two equivalents of aqueous NaOH... 

Silver lactate [128-00-7] M 196.9, m - 100 . Recrystd from H2O by adding EtOH. The solid was collected washed with EtOH then Et20 and dried at 80° to give the dihydrate. White powder soluble in 15 parts of H2O but only slightly soluble in EtOH. [Justus Liebigs Ann Chem 63 89 I847 Helv Chim Acta 2 251 79/9.]...

The main purpose of pesticide formulation is to manufacture a product that has optimum biological efficiency, is convenient to use, and minimizes environmental impacts. The active ingredients are mixed with solvents, adjuvants (boosters), and fillers as necessary to achieve the desired formulation. The types of formulations include wettable powders, soluble concentrates, emulsion concentrates, oil-in-water emulsions, suspension concentrates, suspoemulsions, water-dispersible granules, dry granules, and controlled release, in which the active ingredient is released into the environment from a polymeric carrier, binder, absorbent, or encapsulant at a slow and effective rate. The formulation steps may generate air emissions, liquid effluents, and solid wastes. 

There Is thus obtained 60 g of a white crystalline powder soluble in water. Yield 66%. Melting point 160°C. 

After evaporation of the solvent, a very thick, colorless oil is obtained. This base is dissolved by 200 ml of absolute ethanol and the quantity of HCI to obtain the dihydrochioride is added. It is left for a few hours over ice, dried, washed with approximately 100 ml of anhydrous ether in order to obtain 190 to 195 grams of 1-[2-phenyl-2-methoxy]-ethyl-4-[3-phenyl-3-hydroxy] -propyl-piperazine dihydrochioride after drying at 60°C in vacuo. The yield is 80%. It is recrystallized from absolute ethanol. The product is in the form of white crystalline powder, soluble in water, slightly soluble in alcohol, insoluble in ethyl acetate. 

A solution of the amide chloride (4.6 g) in dry, alcohol-free chloroform (20 ml) was added slowly to a solution of trimethylsilyl 6-amino-penicillanate (7.2 g) and triethylamine (3.5 ml) in dry, alcohol-free chloroform (50 ml) with stirring and cooling to -70°C. The temperature was raised to 0°C during 1V4 hours. The solution was evaporated to dryness in vacua and the residue was triturated with dry ether (200 ml). The precipitate was filtered off and washed with dry ether. The filtrate was diluted with ether (200 ml). 2-Butanol (2.8 ml) was added dropwise with stirring and cooling to0°C. The stirring was continued for A hour at 0°C, whereupon the precipitate was filtered off, washed with ether and dried. It was a white, amorphous powder, soluble in water. 

Sodium hydroxide (NaOH) (caustic soda) Potassium hydroxide (KOH) (caustic potash) Calcium hydroxide (Ca(OH)2) (slaked lime) Ammonium hydroxide (NH4OH) (aqueous ammonia solution) White deliquescent solid.
