Sorbitol 2,4-methylene

This indicator possesses the advantage that it may be used under aerobic conditions, in contrast to dyes such as methylene blue (115). Resazurin has also been applied in the study of the dehydrogenation of isopropanol and sorbitol (103), (118). 

Iodo-desoxy derivatives of methylene, benzylidene and isopropylidene compounds have been transformed into their desoxy analogues with Raney nickel and hydrogen in basic media (e.g. hydroxides, methoxides and diethylamine). 0 47,60,81,82 Under similar conditions, l,3 2,4-diben-zylidene-5,6-sorbitoleen has been hydrogenated 8 and 2,4-benzylidene-6-nitro-6-desoxy-D-sorbitol has been converted into the corresponding amine.84 We are not aware of any report in this field of the removal of a benzylidene group by Raney nickel, as is the case with certain sugar derivatives.88... 

A second dimethylene-D-sorbitol is also known it is the 2,4 3,5-compound (m. p. 192-193°), which was reported almost simultaneously by Haworth and Wiggins52 and by Hann, Wolfe and Hudson.44 In each case the synthesis involved the methylenation and subsequent saponification... 

They found that these rules complied with the structures that were then known for the methylene acetals of sorbitol, mannitol, dulcitol, iditol, 6-desoxy-sorbitol, xylitol and ribitol. From the rules they predicted structures for methylene acetals of allitol and talitol, and several of these predicted acetals have been discovered in later researches. Among the...

The paper-like material consists of the following components (by weight) com starch 62%, poly(propylene-ethylene) 20%, polyethylene 7%, carbamide 1.8%, substituted bis(phenyl methylene) sorbitol (i.e., nucleating agent TM-3) 0.2%, epoxidized soybean oil 2.5%, polyester plasticizer 0.65%, antioxidant 2246 i.e., 2,2-methylene-bis(4-methyl-6-tert-butyl phenol) 0.5%, zinc stearate 0.7%, microciystalline wax 1.5%, calcium stearate 1.3%, talc 1.0%, and stearic acid 0.85%. ... 

Nucleating agents may improve stiffness of the rotomolded part." The following nucleating agents are suggested 4-tert-butylbenzoic acid adipic acid diphenylacetic acid sodium salt of methylene bis-2,4-dibutylphenyl cyclic phosphate esters sorbitol tris-ben-zaldehyde acetal and sodium salt of bis(2,4-di-t-butylphenyl) phosphate or Na salt of eth-ylidene bis(2,4-di-t-butyl phenyl)phosphate." ... 

High speed spinning procedures for the manufacture of high denier polypropylene fibers and yams require application of nucleating agerrls, such as dibenzylidene sorbitol, para-methyldibenzylidene sorbitol, bis-(3,4-dimethyl benzylidene) sorbitol, and sodium 2,2 -methylene-bis-(4,6-di-t-butylphenylene) phosphate. They are used in concentration of 2500-3000 ppm. ... 

Low-shrink polypropylene fibers requires presence of additive that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and allowing such a melt to cool." The preferred rigidifying compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as sodium benzoate, certain sodium and lithium phosphate salts (such as sodium 2,2 -methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11)."... 

A pressure-sensitive adhesive sheet with release liner contains nucleating agent. The nucleating agent can be selected from a group, including alumiinun hydroxy-di-p-tert-butylbenzoate, (sodium 2,2-methylene-bis-(4,6-di-tert-butylphenyl) phosphate, and sorbitol compound. ...
