摘要:
The invention describes basic calcium aluminum hydroxide dicarboxylates of the general formulaCa.sub.x Al.sub.2 (OH).sub.2(x+2) A . m H.sub.2 Owhereinx means 2-8,m means 0-12 andA means an aliphatic, aromatic or heteroaromatic dicarboxylic acid anion or combinations thereofand a process for their production.The compounds according to the invention are especially suited as stabilizers for halogen-containing, thermoplastic resins, in particular PVC.
摘要:
A process for the production of 6-alkoxy-5,6-dihydro-4H-pyrans by reaction of Alpha , Beta -unsaturated aldehydes with vinyl ethers. The products are valuable intermediates, for example for the production of glutaraldehyde or substituted glutaraldehydes which may be used for example as tanning agents for leather.
