Following the findings of Mino and Kaizerman [51] that ceric ion can form a redox system with cellulose, grafting onto various natural polymers has been carried out by the ceric ion method. In the case of cellulose, the reaction between ceric ion and cellulose occurs to produce active sites on cellulose in the following manner  [c.487]

The use of ceric ions to initiate graft polymerization was first discussed by Mino and Kaizerman in 1958 [12]. Schwab and coworkers [13] were among the first to extend this method to the grafting of cellulose. Following their work, numerous papers have appeared in the literature on the grafting of vinyl monomers onto cellulose by this technique.  [c.503]

Mino and Kaizerman [12] established that certain. ceric salts such as the nitrate and sulphate form very effective redox systems in the presence of organic reducing agents such as alcohols, thiols, glycols, aldehyde, and amines. Duke and coworkers [14,15] suggested the formation of an intermediate complex between the substrate and ceric ion, which subsequently is disproportionate to a free radical species. Evidence of complex formation between Ce(IV) and cellulose has been studied by several investigators [16-19]. Using alcohol the reaction can be written as follows  [c.503]

Sulfate Extraction of Beryl. The KjeUgren-Sawyer sulfate process (9) is used commercially for the extraction of beryl. The ore is melted at 1650°C and quenched by pouring into water. The resulting noncrystalline glass is heat-treated at 900—950°C to further increase the reactivity of the beryUium component. After grinding to less than 74 p.m (200 mesh), a slurry of the powder in concentrated sulfuric acid [7664-93-9] is heated to 250—300°C converting the beryUium and aluminum to soluble sulfates. The sUica fraction remains in the dehydrated, water-insoluble form. The nearly dry mass is leached with water using a countercurrent decantation washing procedure and the resulting solution is fed to the same type of solvent extraction process as that used for bertrandite extraction.  [c.66]

Extrinsic Pathway. Coagulation is initiated when tissue extracts with Hpid—protein properties are released from the membranes of endothehal cells following injury or insult. These substances, collectively designated tissue thromboplastin, complex with circulating Factor VII and in the presence of calcium ions subsequentiy activate Factor X (Fig. 1). In vitro evidence suggests that Factor X can be activated less rapidly through the interaction of kaUikrein [9001-01-8] with Factor VII.  [c.172]

Styrene oxide [96-09-3] M 120.2, b 84-86 /16.5mm, d 1.053, n 1.535. Fractional distn at reduced pressure does not remove phenylacetaldehyde. If this material is present, the styrene oxide is treated with hydrogen under 3 atmospheres pressure in the presence of platinum oxide. The aldehyde, but not the oxide, is reduced to 6-phenylethanol) and separation is now readily achieved by fractional distn. [Schenck and Kaizermen J Am Chem Soc 75 1636 1953.]  [c.353]

Research efforts aiming to quantify the solubility of CO2 in ionic liquids revealed a significant influence of the ionic liquid s water content on the CO2 solubility. While water-saturated [BMIM][PF6] (up to 2.3 wt% water) has a CO2 solubility of only 0.13 mol fraction, 0.54 mol fraction CO2 dissolves in dry [BMIM][PFg] (about 0.15 wt% water) at 57 bar and 40 °C [7]. Kazarian et al. used ATR-IR to determine the solubility of CO2 in [BMIM][PFg] and [BMIM] [BFJ. They reported a solubility of 0.6 mol fraction CO2 in [BMIM][PFg] at 68 bar and 40 °C [8].  [c.282]
