Saccharin volume

Nominal syrup ratio is 1 volume syrup plus 5.4 volumes water (15.625% syrup). Maximum concentration occurs when syrup quantity is +5% of target and water quantity is —5% of target, i.e. maximum drink composition is 1.05 volumes syrup plus 5.13 volumes water (16.99% syrup). Thus to ensure a maximum saccharin content of 80 mg/1 in the drink, the syrup must contain a maximum of (80 X 100)/16.99 mg/1 of saccharin, i.e. = 470.9 mg/1. 

This dilution is effected by running the necessary volume of the saccharine liquid from a burette into a ioo c.c. flask and making up to the mark with water. The liquid thus diluted is placed in a burette and various tests made with Fehling s solution and with different volumes of the liquid, as already described (see Sugars, General Methods), until with two quantities of the liquid differing by o-i c.c., in one case only is a trace of copper detectable in the filtrate. 

The mean of these two last determinations gives the volume a c.c. of the diluted saccharine liquid necessary to reduce completely io c.c. of Fehling s solution diluted with 40 c.c. of water. If n represents the number of volumes of dilute saccharine liquid obtained from 1 vol. of wine, the reducing sugars g per litre of wine, calculated as invert sugar, are given by the formula ... 

These results will be used to construct a standard response curve for caffeine, saccharin, and benzoate. Since precision is a function of the volume... 

The major use of phthalic anhydride is for ester derivatives used as plasticizers in the manufacture of flexible poly(vinyl chloride), e.g., wallpaper. The largest volume plasticizer is the di(2-ethylhexyl)phthalate. Other uses of phthalic anhydride are for unsaturated polyester and alkyd resins, for dye intermediates, and for isatoic anhydride (for the production of saccharin).

This work on the isomerization of D-glucose was responsible for the intensive interest which Sowden developed in saccharinic acids. From Schaffer s work, Sowden learned of the relative ease of isolation of saccharinic acids from isoraerized solutions. As a result, Miss Dorothy J. Kuenne was started on an investigation of the mechanism of formation of saccharinic acids, and the first report of this work was published in 1953. In the next few years, six additional investigations were reported in which specially labeled sugars played an important role. To Volume 12 of this Series, Sowden contributed a review on saccharinic acids which presents a clear and impressive account of the state of this complex area of sugar chemistry.

A potentiometric determination of saccharin was proposed by Fatibello-Filho et al. [86]. In this method, saccharin was potentiometrically measured using a silver wire coated with a mercury film as the working electrode. With this, the main difficulty was the presence of a precipitate (mercurous saccharinate) that could adsorb on tube walls and the electrode surface. To avoid these undesirable effects, a relocatable filter unit was placed before the flow-through potentiometric cell and a surfactant was added to the carrier solution (Figure 24.12). The same investigation team reported the construction and analytical evaluation of a tubular ion-selective electrode coated with an ion pair formed between saccharinate anion and toluidine blue O cation incorporated on a poly(vinyl chloride) matrix [87]. This electrode was constructed and adapted in a FIA system. The optimum experimental conditions found were an analytical path of 120 cm, an injection sample volume of 500 pL, a pH of 2.5, a flow rate of 2.3 mL/min, and a tubular electrode length of 2.5 cm. 

A FIA indirect method was described for saccharin determination by Yebra et al. [88]. This method was based on the precipitation of silver saccharinate in an acetic acid medium. The precipitate was dissolved in ammonia, and the dissolved silver was continuously measured by FA AS. The FIA precipitation-dissolution manifold used is similar to that used for cyclamate determination [83] however, in this work, a Scientific System 05-105 column fitted with a removable screen-type stainless-steel filter (pore size 0.5 pm, chamber inner volume 580 pL, filtration area 3 cm ), originally designed as a cleaning device for liquid chromatography, was employed for filtration purposes. 

Weigh 0 5 g into a separator with 10 ml of water, add 2 ml of dilute hydrochloric acid and extract the precipitated saccharin with 30, 20, 20, 20 and 20 ml of a mixture of 9 volumes of chloroform and 1 volume of 95 per cent ethanol, filtering each extract through a small filter paper rinsed with the solvent. Evaporate the filtrates to dryness, on a water-bath under a current of air, and dissolve the residue in 75 ml of hot water. Cool and titrate with O IN sodium hydroxide using phenolphthalein as indicator. 1 ml O IN - 0 02022 g Ci4H806N2S2Ca.
