摘要: THIS INVENTION RELATES TO A METHOD FOR PREPARING CARBOHYDRATE-BORON ALKOXIDE COMPOUNDS. UNDER ANHYDROUS CONDITIONS, STABLE COMPOUNDS OF METHYL CELLULOSE AND BORON ALKOXIDES, SUCH AS BORON ETHOXIDE, BORON PROPOXIDE, AND BORON ISOPROPOXIDE, WERE PREPARED IN NEAT BORON ALKOXIDE, THE PARENT ALCOHOL, BENZENE, PYRIDINE, AND/OR ETHYLENEDIAMINE. THE METHOD OF THIX INVENTION HAS AS ITS OBJECTIVE INCREASING THE REACTIVITY OF METHYL CELLULOSE WITH BORON ALKOXIDES BY TREATMENT IN SOLUTIONS OF STRONG BASES, SUCH AS PYRIDINE AND ETHYLENEDIAMINE. FORMATION OF METHYL CELLULOSE-BORON ALKOXIDE COMPOUNDS MODIFIES THE RATE OF OXIDATION OF METHYL CELLULOSE AND IS RELATED TO PREPARING FLAME-RESISTANT PRODUCTS.

摘要: Fibrous cotton cellulose boron isoproxide or boron propoxide. Under anhydrous conditions, stable compounds of cotton cellulose and boron isopropoxide or boron propoxide were prepared in the neat boron alkoxide, the parent alcohol, benzene, pyridine, and/or ethylenediamine. The method of this invention has as its objective increasing the reactivity of the cotton cellulose with boron isopropoxide or boron propoxide by treatment in solutions of strong bases, such as pyridine and ethylene diamine. Formation of the fibrous cotton cellulose-boron isopropoxide or boron propoxide modifies the rate of oxidation of the cotton cellulose and is related to preparing flame resistant products.
