In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Formula: C3H8O2, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 4254-15-3, name is (S)-Propane-1,2-diol. In an article£¬Which mentioned a new discovery about 4254-15-3
Liquid crystal phase
Liquid crystal phases containing at least one optically active compound of the formula I STR1 wherein X1 and X2 independently of one another are each –CO–O– or –O–CO–, one of X1 and X2 may also be –O–, R1 and R2 independently of one another are each a group –(A1 –Z)m –(A2)n –Y, wherein A1 and A2 in each case independently of one another are a 1,4-phenylene, pyrimidine-2,5-diyl, pyrazine-2,5-diyl, pyridine-2,5-diyl, 1,4-cyclohexylene, 1,3-dioxane-2,5-diyl, 1,3-dithiane-2,5-diyl or 1,4-bicyclo(2,2,2)-octylene group, it also being possible for this to be monosubstituted or polysubstituted by F, Cl, Br, CN and/or alkyl groups with up to 12 C atoms, and it being possible for 1 or 2 non-adjacent CH2 groups in the alkyl groups to be replaced by 0 atoms, Z is –CO–O–, –O–CO–, –CH2 CH2 –, –OCH2 –, –CH2 O–, –CH=N–, –N=CH–, –N=N–, –N(O)=N– or a single bond, m and n in each case independently of one another are 0, 1 or 2, Y is independently of one another a straight-chain or branched alkyl group with up to 12 C atoms, it being possible for 1 or 2 non-adjacent CH2 groups to be replaced by 0 atoms, or, if n is 1 or 2, also F, Cl, Br or CN, R0 is an alkyl group with up to 5 C atoms or a phenyl group or a cyclohexyl group, display largely temperature-independent electrooptical parameters.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 4254-15-3
