A process for the preparation of lactofen

The invention discloses a preparation method of lactofen. The preparation method of lactofen comprises the following steps: carrying out esterification reaction on acifluorfen and 2-ethyl chloropropionate in an organic solvent in the presence of acid-binding agents, thereby obtaining the lactofen after complete reaction and aftertreatment, wherein the acid-binding agents are at least one of potassium hydroxide, sodium hydroxide, sodium tripolyphosphate, borax anhydrous, CaO, sodium metasilicate, sodium orthosilicate and sodium acetate. According to the invention, special acid-binding agents are selected for replacing potassium carbonate and triethylamine, so that carbon dioxide gas is prevented from generating; the reaction system is more stable; meanwhile, the emission of pollutants is reduced; the environment is protected.

Treatment of skin conditions by use of PPAR alpha activators

Disorders of the skin and mucous membrane that have a disrupted or dysfunctional epidermal barrier are treated or prevented by topical application of compounds that are either activators of the farnesoid X receptor, activators of the peroxisome proliferator-activated receptor alpha , and oxysterol activators of the LXR alpha receptor. The same compounds are also effective in treating disorders of epidermal differentiation and proliferation.

Alkylsiloxanes as adjuvants for agriculture

Linear alkylsilicone compounds of the formula STR1 wherein x=0 to 20, preferably 0 to 10, most preferably 0 to 1; y=1 to 10, preferably 1 to 5, most preferably 1; and R is an alkyl or alkyl ester group containing 6 to 16 carbons, or cyclic alkylsilicone compounds of the formula STR2 where m is 0 to 4, preferably 0 to 2, most preferably 0, and n is 1 to 5, preferably 3 to 5, most preferably 4, provided that m+n=3 to 5, are adjuvants for agricultural applications of oil-containing compositions. Especially preferred alkylsilicone compounds have a degree of polymerization of ≤6 and an alkyl content of ≤50% by weight. The compounds potentiate spreading of mineral or vegetable oils or oil-containing emulsions in dormant spray oils, crop oil concentrates, pesticides, and the like on difficult-to wet surfaces such as waxy leaf cuticles and arthropod exoskeletons.
