Strigol and some of its synthetic precursors and analogs are known to be germination stimulants for broomrape (Orobanche ramosa) and witchweed (Striga asiatica). Fifteen synthetic terpenoids, similar in structure to one of the four rings of the strig

Hydrolysis resistance of an N-methylol finish in acidic solutions can generally be predicted based on chemical factors, i.e., electronic effects of substituent groups on the intermediate immonium-carbonium ion, but other factors can produce unexpecte

Concentrations of methylol carbamates in several crosslinking formulations prepared from methyl carbamate and formaldehyde and with and without urea or ethyleneurea as scavengers were determined by nuclear magnetic resonance spectroscopy. The scaveng

Reaction mechanisms for conventional chemical finishing treatments for cotton and hydrolysis of these finishes involving acetals, aldehydes, or N-methylol finishing agents are similar in that the rate-determining step involves the formation of a res

Residues remaining after drying and curing cotton fabric with either sodium bisulfate or zinc nitrate and N-methylolpyrrolidone, a monofunctional model durable press agent, have been quantitated by high performance liquid chromatography. The residues

Variables were studied that affect the rate of formaldehyde release from cotton fabrics finished for durable press. With dimethyloldihydroxyethyleneurea as the crosslinking agent, both the catalyst type and concentration are important. Catalysts of p

A model N-methylol reactant system based on pyrrolidone derivatives has been used to study the chemical factors that control formaldehyde release. Fabric samples of known composition were prepared from chemically pure reactants and formaldehyde relea

Thirty compounds that are precursors, analogs, derivatives, or fragments of strigol were prepared and tested for their activity as witchweed [Striga asiatica(L.) Kuntze] seed-germination stimulators. Five compounds showed significant stimulatory acti
