    摘要： Itaconic acid is prepared by hydrogen cyanide addition to 2-(3hydroxy-2-propenyl)-4,4-dialkyl-2-oxazoline in the presence of a solvent and an alkaline catalyst, dehydrating the resulting product at 70*-140* C. in the presence of a lower aliphatic carboxylic acid or anhydride or mixture thereof, hydrolyzing under reflux conditions with an aqueous mineral acid, and recovering the itaconic acid produced or recovering isomers which are convertible to itaconic acid. Also, novel intermediates resulting from the above cyanide addition and subsequent dehydration are disclosed.

    摘要： A process for the production of hydroxymethyl vinyl oxazolines corresponding to the formula:

    WHERE R is methyl, ethyl, or hydroxymethyl and R'' is hydrogen or methyl, comprising reacting an alkanolamine, in which to the carbon atom adjacent to the amino group there are bonded three hydroxyalkyl groups, or two hydroxyalkyl groups and an alkyl group, with an ester of acrylic acid or methacrylic acid in the presence of a catalyst and a polymerization inhibitor, thereby forming an amide, and heating said amide rapidly and briefly to within about 165*-210* C in the presence of additional polymerization inhibitor, thereby forming said hydroxymethyl vinyl oxazoline.

    摘要： THE PRESENT INVENTION IS DIRECTED TO THE USE OF COMPOSITIONS OF MATTER HAVING THE FORMULA

    2-(R1-X-),4,4-DI(R-)-2-OXAZOLINE

    WHEREIN R IS-CH2OH, LOWER ALKYL HAVING 1 UP TO ABOUT 3 CARBON ATOMS OR-CH2OOCR2, R2 IS AN ALKYL HAVING 1 UP TO ABOUT 22 CARBON ATOMS OR FLUOROALKYL HAVING 1 UP TO ABOUT 22 CARBON ATOMS; R'' IS AN ALKYL HAVING 1 UP TO ABOUT 21 CARBON ATOMS OR FLUOROALKYL HAVING 1 UP TO ABOUT 21 CARBON ATOMS WHEREIN NOT LESS THAN 75% OF THE HYDROGEN ATOMS HAVE BEEN REPLACED BY FLUORINE ATOMS, AND WHEREIN AT LEAST 2 OF THE HYDROGEN ATOMS ON AT LEAST ONE TERMINAL CARBON ATOM HAVE BEEN REPLACED BY FLUORINE ATOMS WITH THE PROVISO THAT WHEN R'' IS AN ALKYL RADICAL AT LEAST ONE OF THE SUBSTITUENTS DESIGNATED R IS THE RADICAL-CH2OOCR2 AND THE SUBSTITUENT R2 IS A FLUOROALKYL RADICAL HAVING 1 UP TO ABOUT 22 CARBON ATOMS WHEREIN NOT LESS THAN 75% OF THE HYDROGEN ATOMS HAVE BEEN REPLACED BY FLUORINE ATOMS, AND WHEREIN AT LEAST 2 OF THE HYDROGEN ATOMS ON AT LEAST ONE TERMINAL CARBON ATOM HAVE BEEN REPLACED BY FLUORINE ATOMS; AND X IS A DIVALENT RADICAL SUCH AS

    -CH2-, -CF2-, -CH(-F)-, OR >C=CH-R9

    WHEREIN R9 IS HYDROGEN, ALKYL OR ARYL, TO PROVIDE OILREPELLENT FIBROUS MATERIALS. IT IS ALSO DIRECTED TO A METHOD FOR THE PREPARATION OF OIL-REPELLENT FIBROUS MATERIALS FROM COMPOSITIONS OF THE FORMULA

    2-(R3-A-),4,4-DI(R4-)-2-OXAZOLINE

    WHEREIN R3 IS IS A FLUOROALKYL RADICAL HAVING 1 UP TO ABOUT 21 CARBON ATOMS WHEREIN NOT LESS THAN 75% OF THE HYDROGEN ATOMS HAVE BEEN REPLACED BY FLUORINE ATOMS AND WHEREIN AT LEAST 2 OF THE HYDROGEN ATOMS ON AT LEAST ONE TERMINAL CARBON ATOM HAVE BEEN REPLACED BY FLUORINE ATOMS; R4 IS-CH2OH, LOWER ALKYL HAVING 1 UP TO ABOUT 3 CARBON ATOMS OR-CH2OOCR5; R6 IS A FLUOROALKYL RADICAL HAVING FROM ABOUT 2 TO ABOUT 22 CARBON ATOMS WHEREIN NOT LESS THAN 75% OF THE HYDROGEN ATOMS HAVE BEEN REPLACED BY FLUORINE ATOMS, AND WHEREIN AT LEAST 2 OF THE HYDROGEN ATOMS ON AT LEAST ONE TERMINAL CARBON ATOM HAVE BEEN REPLACED BY FLUORINE ATOMS; AND A IS

    -CH2-, -CF2-, OR -CH(-F)-

    BY REACTING AN AMINO ALCOHOL OF THE FORMULA

    (G)2-C(-NH2)-CH2-OH

    WHEREIN G IS LOWER ALKYL HAVING 1 UP TO ABOUT 3 CARBON ATOMS OR-CH2OH WITH A FLOROALKYLMONOCARBOXYLIC ACID HAVING FROM ABOUT 3 TO ABOUT 23 CARBON ATOMS WHEREIN NOT LESS THAN 75% OF THE HYDROGEN ATOMS HAVE BEEN REPLACED BY FLUORINE ATOMS AND WHEREIN AT LEAST 2 OF THE HYDROGEN ATOMS ON AT LEAST ONE TERMINAL CARBON ATOM HAVE BEEN REPLACED BY FLUORINE ATOMS.
