TextSentencer_T1 0-139 Sentence denotes New 6-butylamino-6-deoxycellulose and 6-deoxy-6-pyridiniumcellulose derivatives with highest regioselectivity and completeness of reaction.
TextSentencer_T2 140-272 Sentence denotes This paper investigates the nucleophilic substitution (S(N)) reactions of tosylcellulose with butylamine and pyridine, respectively.
TextSentencer_T3 273-684 Sentence denotes The S(N) reactions of tosylcellulose 1 (DS(Total) 2.02; DS(C-6) 1.0) with butylamine carried out at 25, 50, 75 and 100 degrees C in both dimethyl sulfoxide (DMSO) and pure butylamine showed that the regioselectivity of substitution at C-6 of cellulose is temperature dependent: the highest regioselectivity at C-6 can be reached at 25 and 50 degrees C; substitution at C-2 also occurred at 75 and 100 degrees C.
TextSentencer_T4 685-772 Sentence denotes The substitution speed in pure butylamine is greater than that in the presence of DMSO.
TextSentencer_T5 773-910 Sentence denotes A complete and regioselective substitution at C-6 with a DS of 1.0 was obtained under the conditions of 50 degrees C, 40 h in butylamine.
TextSentencer_T6 911-1031 Sentence denotes The substitution reactions of 1 with pyridine carried out at 25, 50, 75 and 100 degrees C for 24h in DMSO did not occur.
TextSentencer_T7 1032-1229 Sentence denotes In contrast to this the S(N) reactions done in pure pyridine showed that a temperature- and steric-dependent, regioselective substitution took place at C-6 at temperatures from 25 to 145 degrees C.
TextSentencer_T8 1230-1383 Sentence denotes The highest regioselectivity and completeness at C-6 can be obtained at 100 degrees C for 90 h, whereas at 145 degrees C substitution also occurs at C-2.
TextSentencer_T9 1384-1443 Sentence denotes The results were proved by 1H NMR and 13C NMR spectroscopy.
