Alcaly

It is clear that this changes on the cell wall must have important consequences on the firmness of the fruit. The breakdown of linkages between pectic polysaccharides and the matrix is likely to be an important factor on the irreversible loss of firmness. The deesterification of polysaccharides, on the other hand could have an effect of increasisng firmness. There is, however, another factor that should be taken into account, the alcali deesterification of the...

Henry Cavendish, in an investigation of the water of Rathbone Place in 1767, speaks of using as much fixed alcali, as was equivalent to 46 0 grains of calcarous earth, ue. which would saturate as much acid. ... 

Grind very finely a considerable amount of the ashes from the rotten oak tree—quercm putrida—and mix them intimately with a sixth part of quicklime. Place a thick cloth over a cask, and on this put the mixture of ashes and lime. Pour boiling water over the mixture, and wash the ashes well. Allow the lye to settle in the cask until the next day. Clarify by filtration. Boil down the lye in a cauldron until all the water has evaporated and fumes are no longer evolved. Let the mass cool, and there will remain a hard stone which is called alcali.

Take for one pound of ore, or what you wish to melt, two pounds granulated lead, five Lot (2l/o oz) salt, five Lot sal alcali, a lye made from willow ashes and quick lime, five Lot corpus mortuus, that is the mud or residue from parting water, five Lot argol (tartar) and heat in a Viennese crucible, and cover it so that nothing unclean may fall into it, and let it fuse in the blast to a regulus (Konig) which then test. ... 

I cannot acquiesce, [says Boyle] in this hypothesis of alcali and acidum, in the latitude wherein I find it urged and applied by the admirers of it, as if it could he usefully substituted in the place of matter and motion. 

An anionic technique by indirect grafting was proposed for N-metallation of Nylon by Yamaguchi (153-155), in which alcali metals dissolved in liquid ammonia displace the amidic hydrogen atoms. Nylon derivatives and graft copolymers can be synthetized from the N-metallated Nylon (153). For ethylene oxide as grafting monomer, the metallated fibers were soaked in a tetrahydro-furan solution of the monomer, at 60° C (154). Methyl methacrylate is grafted on Nylon with a conversion over 90% by this technique (155). Other procedures involve the use of sodium methoxide in methanol solution and subsequent anionic graft copolymerization of acrylonitrile in a tetrahydrofuran solution (156).
