PROBLEM TO BE SOLVED: To provide an amine compound as a charge transporting substance which can form a printed image excellent in clarity without image defects (for example, a dot defect in the halftone and formation of fogging) even when a number of prints are made with the use of an ...
Industrial ethyl mercaptan (C2H5SH), which is characterized by a sharp, unpleasant odor sometimes resembling that of rotten cabbage, is used in the USSR for odorization of natural, shale, and liquefied hydrocarbon gases. As of 1974, work was under way on the introduction of Sul’fan, a high...
Use of a composition (Q) comprising at least a polyaldimine compound of formula (A-(N=CH-C(Y 1>)(Y 2>)(Y 3>)) n) (I), and at least a polyisocyanate as primer for an adhesive agent and sealing agent, is claimed. A : a primary aliphatic amine after removing n primary amino ...
The work of Wong and Wu [135] demonstrates convincingly that solid-state 23Na NMR should be a very useful technique for direct detection of Na+ binding to organic and biological compounds. The high sensitivity of 23Na NMR is a tremendous advantage for applications to biological macromolecules. ...
PREPARATION:A compd. of formula II is reacted with an alkylating agent (e.g., diethyl sulfate) to obtain the compd. of formula I. Alternatively an amine of formula III is diazotized and then coupled with 1-ethyl-4-methyl-6-hydroxy- pyrid-2-one to obtain the compd. of formula I. ...
according to a polarity-based method that enabled sensitive detection of seven primary amines with different alkyl chain lengths, with high discrimination ability down to amine concentrations of 50 ppm (Soga et al., 2013). From a practical perspective, one of the major weaknesses of optical ...
An epoxy adhesive composition of an epoxy resin, an epoxy terminated liquid rubber, filler, and an amine curing package for said epoxy resin is disclosed. Advantageously, a short chain diol will be incorporated into the adhesive in order... MJ Barker - US 被引量: 272发表: 2008年 High ther...
(28) have demonstrated that serum T4S levels exhibit a postnatal tran- sient increase in preterm infants. It is not known whether there is a similar increase in T2S. It would be interesting to study the serum content of preterm infants; an increase in T2S without a significant corresponding...
carbon–halogen bonds, using either an electrophilic fluorinating agent such as Selectfluor™ [1996CRV(96)1737] or elemental fluorine [1997TCC(193)1], or a source of fluoride ion, using an alkali metal fluoride, hydrogen fluoride, or amine hydrofluoride [1992CRV(92)505, 1993T(49)9385]. ...
