Active ester of carboxymethyl cellulose: Active ester of carboxymethyl cellulose. Teshirogi, Takuma (Macromol. Res. Lab., Yamagata Univ., Yonezawa 992, Japan). J. Appl. Polym. Sci., 32(6), 5657-9 (English) 1986. CODEN: JAPNAB. ISSN: 0021-8995. DOCUMENT TYPE: Journal CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Na CM-cellulose [9004-32-4] (substitution degree 2.75) was refluxed 12 h with Et bromoacetate [105-36-2] or bromoacetonitrile [590-17-0] in MeOH-AcNMe2 to give carboxymethyl ethoxycarbonylmethoxycarbonylmethyl cellulose (I) [105697-53-8] or carboxymethyl cyanomethoxycarbonylmethyl cellulose [105697-52-7], resp. I was kept 12 h at 30° with PhCH2NH2 [100-46-9] to give benzylaminocarbonylmethyl CM-cellulose [105697-54-9]. I had potential use as a carrier for enzymes or pharmaceuticals.

Microwave spectrum and molecular structure of bromoacetonitrile: Microwave spectrum and molecular structure of bromoacetonitrile. Gum, M. L.; Graybeal, J. D. (Dep. Chem., Virginia Polytech. Inst., Blacksburg, Va., USA). J. Mol. Spectrosc.In this article, certain chemicals are used. Some of their cas registry numbers are 590-17-0 and 598-21-0 , 62(3), 364-72 (English) 1976. CODEN: JMOSA3. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The ground-state microwave spectrum of BrCH2CN was obsd. and assigned in the P- and R-band regions. For 2 isotopic species a series of strong Q-branch transitions, several clusters of .mu.a-type R-branch transitions, and scattered .mu.b-type and R- and P-branch transitions were fit using both the rigid rotor approxn. and the reduced Hamiltonian of Watson. The hyperfine structure due to the Br atom was analyzed, and the complete field-gradient tensor detd. A least-squares structure consistent with the obsd. rotational consts. exhibited internal consistency and agreed with the structures of similar mols. .
