...through fusing sarcosine, water is evolved, and methylhydautoin is produced, as also an anhydride, formed by the abstraction of one molecule of water from two molecules of sarcosine. Sarcoeine-anhydride, C6H,2N2O3, crystallises in hexagonal colourless plates, melting at... | |

...slowly. Many bases can lose water, with formation of anhydrides or oxides: alcohols behave similarly. By the abstraction of one molecule of water from two molecules of an alcohol, compounds called ethers with the general formula CnH2n+i — O — CnH2n+1 are formed.... | |

...Previous to the year 1912, ordinary oak bark tannin had been regarded as being merely the anhydride formed by the abstraction of one molecule of water from two molecules of gallic acid : 2CeHa(OH),COOH - H,O = CMH10O,. Nobody seemed to doubt the accuracy of this assumption, and all investigations... | |
