Gelatin mass

The purified gum hydrates slowly in water to give viscous solutions at concentrations up to 1% and clear gelatinous masses at higher concentrations. PsyUium seed gum is a laxative additive and is used in cosmetics and in hair-setting lotions. 

The free radicals initially formed are neutralized by the quinone stabilizers, temporarily delaying the cross-linking reaction between the styrene and the fumarate sites in the polyester polymer. This temporary induction period between catalysis and the change to a semisoHd gelatinous mass is referred to as gelation time and can be controUed precisely between 1—60 min by varying stabilizer and catalyst levels. 

If the ester is dry enough to use in this reaction it will not give a gelatinous mass of sodium hydroxide when treated with a little sodium. 

Observations on the polymerization of readily polymerizable vinyl monomers such as styrene, vinyl chloride, and butadiene date back approximately to the first recorded isolation of the monomer in each case. Simon 2 reported in 1839 the conversion of styrene to a gelatinous mass, and Berthelot applied the term polymerization to the process in 1866. Bouchardat polymerized isoprene to a rubberlike substance. Depolymerization of a vinyl polymer to its monomer (and other products as well) by heating at elevated temperatures was frequently noted. Lemoine thought that these transformations of styrene could be likened to a reversible dissociation, a commonly held view. While the terms polymerization and depolymerization were quite generally applied in this sense, the constitution of the polymers was almost completely unknown. 

With ozone, phenylamine forms a triozonide, which separates in the form of a gelatinous mass that is extremely unstable. 

Polymer Synthesis. A solution of 30 mL of (meth)acrylic acid, 5 mol% triethyleneglycol di(meth)acrylate and 0.3 g K2S20g in 300 mL deionized water was stirred and heated at 95°C under N2 for two hours. The gelatinous mass was vacuum dried at 50°C for 48 hours. The polymer was then ground in a Micro-Mill. The portion passing through a 40 mesh screen (<425m) was extracted three times with 80-90°C water and then redried. 

Crystalline solid or amorphos powder exists in two forms, alpha and beta forms the alpha form is a granular powder the beta form is a gelatinous mass of indefinite composition density 1.92 g/cm decomposes to beryllium oxide when heated at elevated temperatures (decomposition commences at 190°C and completes at red heat) practically insoluble in water and dilute alkahes soluble in acids and hot concentrated caustic soda solution. 

Blue crystalline powder or gelatinous mass density 3.36 g/cm decomposes on heating insoluble in cold water Ksp 2.20x10-2° decomposes in hot water soluble in acids, ammonium hydroxide and potassium cyanide. 

Lichenin (Moss Starch). C6H10O5 mw 162.14, mp 10°. White gelatinous mass, resembling starch in props. SI sol in cold w sol in boiling w giving a colloidal soln and sol in HC1. On nitration it yields an expl, Lichenin Penta-nitrate (qv)... 

It was proposed by the duPont Co(Ref 3) to prepare flashless smokeless prop In ts from NC DNT, in which is incorporated ethyl palmttate or other esters of organic acids insol in water but forming a gelatinous mass with NC DNT at about 80°... 

Mix gelatin to uniform consistency with minimal introduction of air. Encapsulate using the drug mixture into 1000 capsules using gelatin mass red opaque and 6.6 m size die roll. 

Encapsulate 425 mg of mixture of step 3 into size 7.5 oval capsules, using gelatin mass clear. 

During fermentation, 30-90% of the pectins are precipitated (5). An analysis of pectin content of wines from native and hybrid varieties (Table IX) for the years 1970 and 1971 indicate a reduction of 75-95% during fermentation. It is probable that the acetone-precipitable material remaining in the wine is gum or partially hydrolyzed pectin since the precipitate, a grey amorphous material, is entirely different from the translucent gelatinous mass typical of precipitated pectin. Although pectin is a problem in hot pressing native and hybrid varieties, the pectin content of the wine is comparable with that of vinifera wine. 

Barium Metarsenite, Ba(As02)3, may be obtained by warming barium chloride with a solution of ammonium arsenite to which acetic acid has been added until arsenious acid is on the point of precipitation. The precipitate is then dried at 100° C.2 It is a white powder, easily soluble in water, but it can also be obtained as a gelatinous mass 3 when a mixture of barium chloride and potassium metarsenite in solution is left to stand for a few hours. On strongly heating it decomposes to form arsenate and free arsenic, but to a much less extent than is the case with the orthoarsenite.4... 

Cerous Monohydrogen Ortkoarsenate, Ce2(HAs04)3, is obtained as a white powder, insoluble in water, by digesting cerous oxide with aqueous arsenic acid.17 It dissolves in excess of the latter and, if the solution is evaporated, a gelatinous mass, probably cerous dihydrogen orthoarsenate, Ce(H2As04)3, is obtained. 

Thallie Orthoarsenate, TlAs04.2H3O, separates as a lemon-yellow gelatinous mass wiien aqueous arsenic acid is added to a solution of thallie nitrate.9 It is insoluble in boiling -water, readily soluble in hydrochloric acid and decomposed by aqueous alkali or ammonia with formation of thallie hydroxide or a basic salt.
