This article is a study of methylene chloride as a substitute for trichloro-fluoromethane in producing flexible polyurethane foam.
chloroform; formaldehyde; methylene chloride; methyl chloride; para ldehyde; formic acid; chloroacetaldehyde.
A large number of structures of benzene methyl and methylene groups but rare aralkyl ether linkage existed in the waste liquor.
Thirteen new compounds of the alkyl styryl indoline spirobenzopyrans were synthesized from the condensation of 2-methylene indoline with the designed salicylaldehyde.
Carbasugars,carbocyclic analogues of true sugars,are compounds in which the ring-oxygen of furanoid or pyranoid sugars is replaced by methylene group.
Most other processes use chemical solvents, like Methylene Chloride or Ethyl Acetate to decaffeinate coffee beans.
The deionizing and deoxidizing water is required by the methylene blue spectrophotometric method in the new national standard to analyze sulfide in water and waste water.
Antioxidative effect of carotenoids on the methylene blue sensitized photoxidation of soybean oil and rapeseed oil was investigated.
The hydroxyl value of epoxy-containing polyester was determined by analyzing acetification principle and using acetyl chloride as acetifier and methylene chloride as solvent.
Methods Three handred and sixty-one patients with acut chlorphenamidine poisoning cases were gastric lavage completely and treated with proper amount of methylene blue and large dose of VitC.
